TGIS_Color is a platform independent color definition used by TatukGIS Developer Kernel. It is defined as little endian ARGB.

Where:

Symbol	Name	Max	Comments
A	Alpha	255	0 means fully transparent; 255 means solid
R	Red	255
G	Green	255
B	Blue	255

Sample colors:

Hex color	Comments
$00000000	Black
$00FFFFFF	Pure Red
$00FF0000	Pure Red
$0000FF00	Pure Green
$000000FF	Pure Blue
$FF000000	Fully transparent; color has no meaning
$80000000	50% transparent black

Each platform has defined conversion functions to convert to/from the actual platform-specific color definition. See TGIS_FrameworkUtils.
