40Description:
41
42Pixel buffer object tests create pixel pack buffer or unpack buffer. Data is
43written to buffer either using glBuffer(Sub)Data() or mapping buffer. After
44the write data is verified to be correct by mapping the buffer. Additionally,
45for pixel pack buffers readpixels is issued with PBO bound. The readpixels result
46is verified by doing the same operation without pack buffer and then comparing
47the results.
