* Please note that this version has been modified for various reasons:
|
|
* 1. Using the Godot core typedefs
|
|
* 2. At some point or another the code relied on the byte order of a uint32_t, this has been fixed
|
|
* 3. Output has been reordered to struct { uint8_t r, g, b, a; } precisely in accordance with the function names
|
|
* 4. Removing unused 'dither' parameter
