A bunch of Mac drawing updates to correct issues and improve performance.
Switched to using a different (faster) method for drawing rectangles.
Fixed subpixel drawing issues related to the fact that drawing occurs centered on the coordinate so adding 0.5 draws at a pixel itself instead of spanning two pixels.
And related to that removing the incorrect workaround I had previously used of setting the line width to 0.5.
Also added DW_DRAW_NOAA support when drawing to windows.
