@Not-Nik Thanks for the improvement! Actually it was on the raylib future plans but it was discarded... I can reconsider it, it looks good. Just added a couple of review comments. |
Updated accordingly |

Makes creation of HDR textures with 16-Bit half floats possible. This needs some minor compatibility changes because in OpenGL ES half float textures are in a separate extension, but it won't change platform support in any major way (the two even have a single entry in Khronos' extension registry).
The image manipulation functions are a bit more complicated, because there is no native half float support in C so I've used two new util functions
HalfToFloatandFloatToHalfthere.This doesn't change the API apart from 3 (6 if you count rlgl) new enum variants.
