-W and -H won't work in embedded mode

[donmor]

Is there an existing issue for this?

• I have searched the existing issues

Are you using any gamescope patches or a forked version of gamescope?

• The issue occurs on upstream gamescope without any modifications

Current Behavior

Recently I'm testing gamescope to see if this can be a new way to get CRT-compliant video for my retro games (I'm using cage before this), and ran into some problems:

The embedded mode, i.e. starting gamescope with drm/kms backend, ignores -W and -H and gets stuck in the native tty resolution. -r is not ignored and weirdly changes the refresh rate (it should be -R as referred in #265 ).

Steps To Reproduce

Launch a game (e.g. dosbox-x) from tty: gamescope -W 640 -H 400 -r 120 -- dosbox-x

Hardware information

- Distro: Ubuntu 22.04
- CPU: AMD A12-9800
- GPU: AMD Radeon RX 550
- Driver Version: Mesa 23.2.1-1ubuntu3.1~22.04

Software information

- Desktop environment: N/A
- Session type: tty
- Gamescope version: 3.11.49-1 (apt package version, `--version` option not recognized)
- Gamescope launch command(s): `gamescope -W 640 -H 400 -r 120 -- dosbox-x`

Which gamescope backends have the issue you are reporting?

• Wayland (default for nested gamescope)
• DRM (default for embedded gamescope, i.e. gamescope-session)
• SDL
• OpenVR

The current upstream version is 3.15.14(reported as 3.15.9 in the binary) not 3.11.49(2 years old), -W and -H work as expected and -R doesn't seem to exist in upstream, not sure if it ever did as that is a issue, not a pull request.
