Add additional resolutions

[elachlan]

Some resolutions seems to be missing. I run an ultrawide and it did not have the correct resolution.

Platform: Windows 64bit

This might be some help:

To add to this, at least with my set up, I could only choose the current system resolution as the resolution to run the benchmark across any of the supported graphics api's. While my aspect ratio would also count as a ultra-wide aspect ratio but even wider then normal (~25:9).
Also using windows 64 bit.

This screenshot probably explains it a bit better.
