[Piglit] [PATCH] util/x11: Propagate window resize events to piglit_width/height

[Chad Versace]

When I switched Piglit from GLUT to Waffle, I broke detection of X11
window resizes. When the user resized the window, Piglit called
piglit_display() but neglected to update piglit_width/height.

This patch ensures that Piglit updates piglit_width/height correctly.

(It's amazing that it took this long for anyone to fix it. People must
rarely resize Piglit windows).
