Coherent mappings have a lower overhead and less GL codes. So enables coherent mapping by default for all drivers. Both Qualcomm and ARM performs very bad with explicit flushing, so this change helps them as well. AFAIK there was one GPU generation which was slower on coherent mapping: nvidia tesla So Geforce 200 and 300 series should be tested with this PR before merging. As this was last tested many years ago, this issue might have been fixed as well. Those GPUs are close to 10 years old and not supported any more by nvidia.
