For screen capture to work with PRIME (laptops with a nvidia gpu), you must set the primary GPU to use your dedicated nvidia graphics card. You can do this by selecting "NVIDIA (Performance Mode) in nvidia settings:\

### TEMPORARY ISSUE
screen-direct capture has been temporary disabled as it causes issues with stuttering. This might be a nvfbc bug.
### TEMPORARY ISSUES
1) screen-direct capture has been temporary disabled as it causes issues with stuttering. This might be a nvfbc bug.
2) Recording monitor on AMD/Intel has been temporary disables as issues surrounding it are fixed.
### AMD/Intel root permission
When recording a window under AMD/Intel no special user permission is required, however when recording a monitor the program needs root permission (to access KMS).
To make this safer, the part that needs root access has been moved to its own executable (to make it as small as possible) and a GUI sudo prompt is shown to run this executable as root. The executable is called "gsr-kms-server".

Support -h and --help. -h should only show the first line and --help the full help. On error, only show that -h.
Rotated display on amd doesn't work correctly (if you only have 1 monitor connected and it's rotated), even with ffmpeg kmsgrab. The drmfd is rotated as well so it needs to be rotated in the surface copy.
Fix kms monitor capture. Broken right now on amd and performance is bad.
