Modern RDP supports a number of improvements in order to boost graphics
performance. We should implement support for these in rdesktop.

> 1. OpenGL 4.4 and OpenCL 1.1 API Support
> Prior to the Windows Server Technical Preview, running a virtual
> machine on Hyper-V limited you to OpenGL 1.1 with CPU
> acceleration and no support for OpenCL regardless of the presence
> of a capable GPU. This was a limiting factor for delivering a
> virtual desktop for users with applications such as Adobe
> Photoshop, Maya, Blender and Houdini which require these
> APIs. With a capable GPU on a Hyper-V host, RemoteFX vGPU now
> delivers support for OpenGL up to version 4.4 and OpenCL 1.1 in a
> Windows virtual machine.
