Description Dan Glastonbury 2022-07-14 19:01:13 PDT 
Some arrays have minimum sizes specified by the OpenGL ES spec and should never be zero. GL_COMBINED_TEXTURE_IMAGE_UNITS and GL_MAX_VERTEX_ATTRIBS have minimum values and should never be 0. When initialising a new context, if these values are 0 that indicates a problem with the GL context. The context is marked as lost to stop further commands from being processed.
