+/*
+ * 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.

+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.
