* OpenGL error checking
*
* By default, only critical errors will get checked in release build
* and critical&common in debug build.
*
* This can get overwritten with a compile flag define:
* -DACGL_CHECK_NO_GL_ERRORS
* No error checking at all
* -DACGL_CHECK_CRITICAL_GL_ERRORS
* Places will get checked where errors like out of memory can occur.
* This will detect runtime errors which can happen even if the program
* is bug free.
* Switching this on shouldn't be a performance hit.
* -DACGL_CHECK_COMMON_GL_ERRORS
* Problems that happen more often while developing like typos in uniform
* names. All placed where strings are used to call OpenGL objects etc.
* -DACGL_CHECK_RARE_GL_ERRORS
* Most likely bugs in ACGL itself or wrong usage. If there are strange errors
* switch this on to find the reason more quickly. Even normal development
* should work without this. Results in a lot of glGetError!
*
* Note that all error levels also include the higher ones (COMMON also adds CRITICAL).
