1.1 Display settings
Internal and fullscreen resolution: Since the only internal resolutions allowed are also
fullscreen resolution allowed by the system there is only need for one resolution setting
that applies to both the internal resolution and the fullscreen resolution.
Todo: Make the internal resolution option apply instantly, currently only the native and 2x option
applies instantly. To do this we need to enumerate all avaliable display resolutions before
Renderer:Init().
1.2 Screenshots
The screenshots should be taken from the internal representation of the picture regardless of
what the current window size is. Since AA and wireframe is applied together with the picture resizing
this rule is not currently applied to AA or wireframe pictures, they are instead taken from whatever
the window size is.
Todo: Render AA and wireframe to a separate picture used for the screenshot in addition to the one
for display.
1.3 AA
Make AA apply instantly during gameplay if possible
