Place surface at screen't top-left when doing drag resizing

Instead of letting the client render to (0,0) and moving the surface
around, put the surface at a fixed location, and let the client render
to the screen position within the surface.

This fixes the window shaking problem when resizing by dragging window's
top-left corner. The frame rect used in last draw is lagging window
manager's latest bounds for the window, moving the surface's position
would make the window's bottom-right corner appears moving (while it's
supposed to be stationary).
