Detailed Description

Bind texture to an image unit (available only if GL version is 4.2 or greater) The format parameter for the image unit need not exactly match the texture internal format, but if it is set to 0, the texture internal format will be used. See http://www.opengl.org/registry/specs/ARB/shader_image_load_store.txt void bindToImageUnit(unsigned int unit, GLenum access, GLenum format=0, int level=0, bool layered=false, int layer=0);
