marxin e5f665c718 Fix -Wsign-compare warnings.
I decided to modify code in a defensive way. Ideally functions
like size() or length() should return an unsigned type.

Hein-Pieter van Braam 9c308023bb Properly detect when to use DRI_PRIME
We fork off twice once with and once without DIR_PRIME=1 set. We
then use the vendor string to determine what GPU to use.

We prefer (in order)
1) AMDGPU/AMDGPU-PRO/NVidia non-free driver
2) Intel driver
3) Nouveau
4) Software rendering

If a driver can't be detected it will default to DRI_PRIME=0
