Subject: SDL1.3: Some X11 diffs

The attached diff fixes the following issues in the X11 backend:

a) When calling resize, actually a move was performed. This has been
corrected.

b) DisplayHeight and DisplayWidth do not return up-to-date information
after a modeswitch using the xrandr code, which I enabled in
x11_modes.c
Height and width are now queried from the root window and all
occurrences of DisplayHeight and DisplayWidth changed.
