~ written close to equivalent versions in OpenGL code using GLM and GLFW ~ written replacements for texture and package loading to not use irrlicht anymore ~ updated shader compiler as we now don't need to replace attributes anymore + added support for texture flags in the texture header (as they're needed for opengl to get proper information) TODO: REWRITE VIDEO PLAYER SUPPORT AS THIS UPDATE EFFECTIVELY BREAKS IT Signed-off-by: Alexis Maiquez <almamu@almamu.com>
