+ * 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.
