Data is 43 written to buffer either using glBuffer(Sub)Data() or mapping buffer. After 44 the write data is verified to be correct by mapping the buffer. Additionally, 45 for pixel pack buffers readpixels is issued with PBO bound. The readpixels result 46 is verified by doing the same operation without pack buffer and then comparing 47 the results. 48
