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