+ * The android_flex_layout structure is used with any pixel format that can be

+ *
+ * Horizontal increment (aka. column or pixel increment) describes the distance
+ * in bytes from one pixel to the next pixel (to the right) on the same row for
+ * the component plane. This can be negative.
+ *
+ * Each plane can be subsampled either vertically or horizontally by

 /*
+ * Color modes that may be supported by a display.
+ *
+ * Definitions:
+ * Rendering intent generally defines the goal in mapping a source (input)
+ * color to a destination device color for a given color mode.
+ *
+ *  It is important to keep in mind three cases where mapping may be applied:
+ *  1. The source gamut is much smaller than the destination (display) gamut
+ *  2. The source gamut is much larger than the destination gamut (this will
+ *  ordinarily be handled using colorimetric rendering, below)
+ *  3. The source and destination gamuts are roughly equal, although not
+ *  completely overlapping
+ *  Also, a common requirement for mappings is that skin tones should be
+ *  preserved, or at least remain natural in appearance.
+ *
+ *  Colorimetric Rendering Intent (All cases):
+ *  Colorimetric indicates that colors should be preserved. In the case
+ *  that the source gamut lies wholly within the destination gamut or is
+ *  about the same (#1, #3), this will simply mean that no manipulations
+ *  (no saturation boost, for example) are applied. In the case where some
+ *  source colors lie outside the destination gamut (#2, #3), those will
+ *  need to be mapped to colors that are within the destination gamut,
+ *  while the already in-gamut colors remain unchanged.
+ *
+ *  Non-colorimetric transforms can take many forms. There are no hard
+ *  rules and it's left to the implementation to define.
+ *  Two common intents are described below.
+ *
+ *  Stretched-Gamut Enhancement Intent (Source < Destination):
+ *  When the destination gamut is much larger than the source gamut (#1), the
+ *  source primaries may be redefined to reflect the full extent of the
+ *  destination space, or to reflect an intermediate gamut.
+ *  Skin-tone preservation would likely be applied. An example might be sRGB
+ *  input displayed on a DCI-P3 capable device, with skin-tone preservation.
+ *
+ *  Within-Gamut Enhancement Intent (Source >= Destination):
+ *  When the device (destination) gamut is not larger than the source gamut
+ *  (#2 or #3), but the appearance of a larger gamut is desired, techniques
+ *  such as saturation boost may be applied to the source colors. Skin-tone
+ *  preservation may be applied. There is no unique method for within-gamut
+ *  enhancement; it would be defined within a flexible color mode.
