Detailed Description

32-bit RGBA colour stored in a union that allows component and packed-integer access.

The byte order of the components within rgba depends on whether the target is big-endian (IS_BIGENDIAN defined) or little-endian. Use the named struct members for portable access and the rgba field only when a packed 32-bit representation is required (e.g. GPU uploads).

Note

Only use the rgba field when alignment requirements demand it.
