GR provides its own (native) logical device drivers ("GKS" workstations)
for X11 (Un*x), Core Graphics (OS X) and GDI (Windows). These drivers were
developed as part of GR (with many other drivers) to achieve more graphics
performance and consistent graphics output. For the X11 driver, however, I
did not yet implement transparency (as provided by the Xrender extension)
knowing that there was already an X11 backend for Cairographics which would
support this. After playing around with the new driver, I no longer have
the expectation that it will be a replacement for the existing native
backends. I will probably use Cairographics "only" for offscreen rendering
and add render extensions to the existing X11 driver - but we'll see ...
The 3D functionality will be available as an alternative to the existing
GR3 layer through a new ModernGL library (still WIP) this summer ...
