+ * Hardware Composer Color Equivalence
+ *
+ * Synopsis
+ *   hwc_colorequiv [options] eFmt
+ *
+ *     options:
+         -v - verbose
+ *       -s <0.##, 0.##, 0.##> - Start color (default: <0.0, 0.0, 0.0>
+ *       -e <0.##, 0.##, 0.##> - Ending color (default: <1.0, 1.0, 1.0>
+ *       -r fmt - reference graphic format
+ *       -D #.## - End of test delay
+ *
+ *     graphic formats:
+ *       RGBA8888 (reference frame default)
+ *       RGBX8888
+ *       RGB888
+ *       RGB565
+ *       BGRA8888
+ *       RGBA5551
+ *       RGBA4444
+ *       YV12
+ *
+ * Description
+ *   Renders a horizontal blend in two frames.  The first frame is rendered
+ *   in the upper third of the display and is called the reference frame.
+ *   The second frame is displayed in the middle third and is called the
+ *   equivalence frame.  The primary purpose of this utility is to verify
+ *   that the colors produced in the reference and equivalence frames are
+ *   the same.  The colors are the same when the colors are the same
+ *   vertically between the reference and equivalence frames.
+ *
+ *   By default the reference frame is rendered through the use of the
+ *   RGBA8888 graphic format.  The -r option can be used to specify a
+ *   non-default reference frame graphic format.  The graphic format of
+ *   the equivalence frame is determined by a single required positional
+ *   parameter.  Intentionally there is no default for the graphic format
+ *   of the equivalence frame.
+ *
+ *   The horizontal blend in the reference frame is produced from a linear
+ *   interpolation from a start color (default: <0.0, 0.0, 0.0> on the left
+ *   side to an end color (default <1.0, 1.0, 1.0> on the right side.  Where
+ *   possible the equivalence frame is rendered with the equivalent color
+ *   from the reference frame.  A color of black is used in the equivalence
+ *   frame for cases where an equivalent color does not exist.

+ * Hardware Composer Commit Points
+ *
+ * Synopsis
+ *   hwcCommit [options] graphicFormat ...
+ *     options:
+ *       -s [width, height] - Starting dimension
+ *       -v - Verbose
+ *
+ *      graphic formats:
+ *        RGBA8888 (reference frame default)
+ *        RGBX8888
+ *        RGB888
+ *        RGB565
+ *        BGRA8888
+ *        RGBA5551
+ *        RGBA4444
+ *        YV12
+ *
+ * Description
+ *   The Hardware Composer (HWC) Commit test is a benchmark that
+ *   discovers the points at which the HWC will commit to rendering an
+ *   overlay(s).  Before rendering a set of overlays, the HWC is shown
+ *   the list through a prepare call.  During the prepare call the HWC
+ *   is able to examine the list and specify which overlays it is able
+ *   to handle.  The overlays that it can't handle are typically composited
+ *   by a higher level (e.g. Surface Flinger) and then the original list
+ *   plus a composit of what HWC passed on are provided back to the HWC
+ *   for rendering.
+ *
+ *   Once an implementation of the HWC has been shipped, a regression would
+ *   likely occur if a latter implementation started passing on conditions
+ *   that it used to commit to.  The primary purpose of this benchmark
+ *   is the automated discovery of the commit points, where an implementation
+ *   is on the edge between committing and not committing.  These are commonly
+ *   referred to as commit points.  Between implementations changes to the
+ *   commit points are allowed, as long as they improve what the HWC commits
+ *   to.  Once an implementation of the HWC is shipped, the commit points are
+ *   not allowed to regress in future implementations.
+ *
+ *   This benchmark takes a sampling and then adjusts until it finds a
+ *   commit point.  It doesn't exhaustively check all possible conditions,
+ *   which do to the number of combinations would be impossible.  Instead
+ *   it starts its search from a starting dimension, that can be changed
+ *   via the -s option.  The search is also bounded by a set of search
+ *   limits, that are hard-coded into a structure of constants named
+ *   searchLimits.  Results that happen to reach a searchLimit are prefixed
+ *   with >=, so that it is known that the value could possibly be larger.
+ *
+ *   Measurements are made for each of the graphic formats specified as
+ *   positional parameters on the command-line.  If no graphic formats
+ *   are specified on the command line, then by default measurements are
+ *   made and reported for each of the known graphic format.

+ *
+ *      displayFrame
+ *        [left, top, right, bottom]
+ *
+ *      attributes:
+ *        transform: none | fliph | flipv | rot90 | rot180 | rot270
+ *        blend: none | premult | coverage
+ *        color: [0.##, 0.##, 0.##]
+ *        alpha: 0.##
+ *        sourceDim: [width, height]
+ *        sourceCrop: [left, top, right, bottom]
+ *
+ *      Example:
+ *        # White YV12 rectangle, with overlapping turquoise
+ *        #  RGBA8888 rectangle at 30%% (alpha: 0.7) transparency
+ *        hwcRects -v -D 30.0 \

+ *            color: [1.0, 0.5, 0.5], \
+ *          RGBA8888 [100, 150, 300, 400] blend: coverage \
+ *            color: [0.251, 0.878, 0.816] alpha: 0.7 \
+ *            sourceDim: [50, 60] sourceCrop: [5, 8, 12, 15]
+ *
+ * Description
+ *   Constructs a Hardware Composer (HWC) list of frames from
+ *   command-line specified parameters.  Then sends it to the HWC
+ *   be rendered.  The intended purpose of this tool is as a means to
+ *   reproduce and succinctly specify an observed HWC operation, with
+ *   no need to modify/compile a program.
+ *
+ *   The command-line syntax consists of a few standard command-line
+ *   options and then a description of one or more frames.  The frame
+ *   descriptions are separated from one another via a comma.  The
+ *   beginning of a frame description requires the specification
+ *   of the graphic format and then the display frame rectangle where
+ *   the frame will be displayed.  The display frame rectangle is
+ *   specified as follows, with the right and bottom coordinates being
+ *   exclusive values:
+ *
+ *     [left, top, right, bottom]
+ *    
+ *   After these two required parameters each frame description can
+ *   specify 1 or more optional attributes.  The name of each optional
+ *   attribute is preceded by a colon.  The current implementation
+ *   then requires white space after the colon and then the value of
+ *   the attribute is specified.  See the synopsis section above for
+ *   a list of attributes and the format of their expected value.

+/*
+ * Hardware Composer stress test
+ *
+ * Performs a pseudo-random (prandom) sequence of operations to the
+ * Hardware Composer (HWC), for a specified number of passes or for
+ * a specified period of time.  By default the period of time is FLT_MAX,
+ * so that the number of passes will take precedence.
+ *
+ * The passes are grouped together, where (pass / passesPerGroup) specifies
+ * which group a particular pass is in.  This causes every passesPerGroup
+ * worth of sequential passes to be within the same group.  Computationally
+ * intensive operations are performed just once at the beginning of a group
+ * of passes and then used by all the passes in that group.  This is done
+ * so as to increase both the average and peak rate of graphic operations,
+ * by moving computationally intensive operations to the beginning of a group.
+ * In particular, at the start of each group of passes a set of
+ * graphic buffers are created, then used by the first and remaining
+ * passes of that group of passes.
+ *
+ * The per-group initialization of the graphic buffers is performed
+ * by a function called initFrames.  This function creates an array
+ * of smart pointers to the graphic buffers, in the form of a vector
+ * of vectors.  The array is accessed in row major order, so each
+ * row is a vector of smart pointers.  All the pointers of a single
+ * row point to graphic buffers which use the same pixel format and
+ * have the same dimension, although it is likely that each one is
+ * filled with a different color.  This is done so that after doing
+ * the first HWC prepare then set call, subsequent set calls can
+ * be made with each of the layer handles changed to a different
+ * graphic buffer within the same row.  Since the graphic buffers
+ * in a particular row have the same pixel format and dimension,
+ * additional HWC set calls can be made, without having to perform
+ * an HWC prepare call.
+ *
+ * This test supports the following command-line options:
+ *
+ *   -v        Verbose
+ *   -s num    Starting pass
+ *   -e num    Ending pass
+ *   -p num    Execute the single pass specified by num
+ *   -n num    Number of set operations to perform after each prepare operation
+ *   -t float  Maximum time in seconds to execute the test
+ *   -d float  Delay in seconds performed after each set operation
+ *   -D float  Delay in seconds performed after the last pass is executed
+ *
+ * Typically the test is executed for a large range of passes.  By default
+ * passes 0 through 99999 (100,000 passes) are executed.  Although this test
+ * does not validate the generated image, at times it is useful to reexecute
+ * a particular pass and leave the displayed image on the screen for an
+ * extended period of time.  This can be done either by setting the -s
+ * and -e options to the desired pass, along with a large value for -D.
+ * This can also be done via the -p option, again with a large value for
+ * the -D options.
+ *
+ * So far this test only contains code to create graphic buffers with
+ * a continuous solid color.  Although this test is unable to validate the
+ * image produced, any image that contains other than rectangles of a solid
+ * color are incorrect.  Note that the rectangles may use a transparent
+ * color and have a blending operation that causes the color in overlapping
+ * rectangles to be mixed.  In such cases the overlapping portions may have
+ * a different color from the rest of the rectangle.

+ *   2. Initialization
+ *
+ *   3. For each pass:

+ *        a. If pass is first pass or in a different group from the
+ *           previous pass, initialize the array of graphic buffers.
+ *
+ *        b. Create a HWC list with room to specify a prandomly
+ *           selected number of layers.
+ *
+ *        c. Select a subset of the rows from the graphic buffer array,
+ *           such that there is a unique row to be used for each
+ *           of the layers in the HWC list.
+ *
+ *        d. Prandomly fill in the HWC list with handles
+ *           selected from any of the columns of the selected row.
+ *
+ *        e. Pass the populated list to the HWC prepare call.
+ *
+ *        f. Pass the populated list to the HWC set call.
+ *
+ *        g. If additional set calls are to be made, then for each
+ *           additional set call, select a new set of handles and
+ *           perform the set call.

+ * When possible, converts color specified as a full range value in
+ * the fromFormat, into an equivalent full range color in the toFormat.
+ * When conversion is impossible (e.g. out of gamut color) a color
+ * or black in the full range output format is produced.  The input
+ * color is given as a fractional color in the parameter named color.
+ * The produced color is written over the same parameter used to
+ * provide the input color.
+ *
+ * Each graphic format has 3 color components and each of these
+ * components has both a full and in gamut range.  This function uses
+ * a table that provides the full and in gamut ranges of each of the
+ * supported graphic formats.  The full range is given by members named
+ * c[123]Min to c[123]Max, while the in gamut range is given by members
+ * named c[123]Low to c[123]High.  In most cases the full and in gamut
+ * ranges are equivalent.  This occurs when the c[123]Min == c[123]Low and
+ * c[123]High == c[123]Max.
+ *
+ * The input and produced colors are both specified as a fractional amount
+ * of the full range.  The diagram below provides an overview of the
+ * conversion process.  The main steps are:
+ *
+ *   1. Produce black if the input color is out of gamut.
+ *
+ *   2. Convert the in gamut color into the fraction of the fromFromat
+ *      in gamut range.
+ *
+ *   3. Convert from the fraction of the in gamut from format range to
+ *      the fraction of the in gamut to format range.  Produce black
+ *      if an equivalent color does not exists.
+ *
+ *   4. Covert from the fraction of the in gamut to format to the
+ *      fraction of the full range to format.

+Repro steps:
+
+build, install and run the attached test program TestViewport.apk
+
+Run on Sapphire with Froyo.
+
+The program clears the screen to blue, then draws a full screen white quad that
+is alligned to the screen.
+(Therefore the whole screen should appear to be white.)
+
+
+Note that screen is all white.
+
+Rotate screen 90 degrees.
+
+Expected: screen is still all white.
+
+Actual: screen is blue with offset white rectangle.
+
+This bug only happens on Sapphire, it works correctly on Passion.
+
+What happens:
+
+I think the bug is that the gl.glViewport() call in onSurfaceChanged() is
+being ignored by the OpenGL driver.
+
+NOTE: If a gl.glViewport call is added at the beginning of the onDrawFrame()
+call (which means it is called before every draw), the program runs correctly.
