Feature: Add functionality to toggle fullscreen with F11

[VoxelTek]

Allows toggling fullscreen in Vanilla by using F11 key.

2026-02-13.15-36-42.mp4

Known issue: if toggling fullscreen with F11 in the Settings menu, the option for Full Screen does not update until the Settings page is reloaded. This could be fixed by including ui.h in menu.c and adding the line vui_button_update_checked(vui, button, vpi_config.fullscreen);.

Closes #345

Probably a good idea to put F11 shortcut before F12 shortcut

Here, it's not really relevant whatsoever what order they're in, no end users are going to be seeing this anyway. Additionally, this should match the order in the enum

My point was not exactly for end users, but for code organization.

Additionally, this should match the order in the enum.

I see, then it makes more sense to keep the order as-is.

Now that we have a key remapping system, can you add an entry for this to menu_gamepad.c

@itsmattkc How's this?

Not quite sure why the full-screen icon isn't being anti-aliased in the same way the screenshot icon is, maybe a weird side effect of how svgs are displayed? Don't know how to fix it, unfortunately.

LGTM, thanks
