We now set deviceScale to always the mapping from logical window system pixels to device independent pixels (which is what Ebiten API users expect), and introduce a new concept of videoModeScale that maps from video mode to logical window system pixels. videoModeScale is now only used for computing full-screen resolutions, while deviceScale is used for any other conversion. Fixes window sizes on X11, should be a NOP otherwise. Closes #1774.
