Fix failing cursor2D test and some minor cleanup

Two issue on this test. The ModelBounds[4] and [5] were
incrorectly being set to ymin and ymax. Bad bro. Also
just some general bad numbers floating around in there.

Second issue the test window was 120 pixels wide. On some
high resolution displays the window title/decoration end up being wider
than 120 pixels causing a valid image mismatch. Increased the
window size to 150 pixels and changed the valid image to match.
