GraphicsBitmap: create_wrapper() should take pitch as a parameter

Browse Source 
We shouldn't assume that the pitch of some arbitrary bitmap memory that
we're wrapping is going to be 16-byte aligned. Instead, just take the
pitch as a parameter.

Also update WindowServer to pass the pitch to the framebuffer bitmaps.
