2D accelerators bundled with GPUs perform 2D rendering ops faster than 
GPUs? Uhmm... that sentence is conflicting in my head, unless you mean 
that you are using highly specialized boards with multiple GPUs (n*PVR) 
on them to do things really really fast in parallel.

Btw, does this means you are trying/wanting to run Qt 5 on PowerVR 
chipsets from before 2001? All the PVR chips since Feb. 2001 (Series 4 
or higher) support some form of OpenGL/GLES and/or DirectX 8.0 or higher 
(ANGLE requires DirectX 9, but maybe it can be tweaked to use 8, Windows 
only of course).

Anyways, probably good to know which 2D boards you're talking about, 
since others in the community might have experience with them, and could 
help out?
