I know, that's one of the many things that's been on my TODO list for ages :)
Some video cards have support for KTX_buffer_region, others only have support
for ARB_buffer_region.. it depends on what card you're using (mostly the
older ones have support for the KTX one, afaik).
Altough they're not exactly the same, it'd be quite easy to support them both.
It also helps making things much faster when dragging another window or dialog
over the viewports (which gives a more polished feeling to the program).
