/*
* 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.

* 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.

/*
* 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.
