Games based on the allegro gaming library or on ClanLib-1.0 do not size
|
|
their window to match the fullscreen resolution, instead they use a
|
|
window covering the entire screen, drawing only the fullscreen resolution
|
|
part of it.
|
|
|
|
This commit adds a check for these games, so that we correctly apply a
|
|
viewport to them making fullscreen work properly for these games under
|
|
Xwayland.
