/*

 * 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.
