i915: Fix off-by-one for drawing rectangle.
The drawing rectangle is given in *inclusive* pixel values, so the range is only [0,2047]. Hence when rendering to a 2048 wide target, such as an extended desktop, we would issue an illegal instruction zeroing the draw area. Fixes: Bug 27408: Primary and Secondary display blanks in extended desktop mode with Compiz enabled https://bugs.freedesktop.org/show_bug.cgi?id=27408 Signed-off-by: Chris Wilson <[email protected]>
