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. - Apparently no, someone else doesn't agree
Todo: Make the internal resolution option apply instantly, currently only the
native and 2x option applies instantly. To do this we need to be able to change
the reinitialize FramebufferManager:Init() while a game is running.
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
