/*
 * OpenGL error checking defines
 *
 * 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_ERROR_LEVEL_EC0
 *    No error checking at all
 *  -DACGL_ERROR_LEVEL_EC1
 *    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_ERROR_LEVEL_EC2
 *    Problems that happen more often while developing like typos in uniform
 *    names. All placed where strings are used to call OpenGL objects etc.
 *  -DACGL_ERROR_LEVEL_EC3
 *    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).
