Unless the application is using PBOs, any call to glReadPixels will hit
this message. Hitting this does mean mapping the buffer and accessing
it via the CPU, but that isn't necessarily the worst thing in the world.
apitrace's image dumping code hits this path, causing it to spam
hundreds of thousands of performance warnings via ARB_debug_output,
which makes it difficult to see actual errors.
