Subject: [PATCH] Change physical screen dimensions when rotating
If the physical screen dimensions are not changed when applying
a rotated mode then the DPI is calculated in correctly. Most
configs do not set this so the default calculated DPI is fine,
however configs that set a custom DisplaySize need this change
to preserve the DPI.
