test: Use smaller boxes in region_contains_test()
The boxes used region_contains_test() sometimes overflow causing
*** BUG ***
In pixman_region32_union_rect: Invalid rectangle passed
Set a breakpoint on '_pixman_log_error' to debug
messages to be printed when pixman is compiled with DEBUG. Fix this by
dividing the x, y, w, h coordinates by 4 to prevent overflows.
