DrawStripedRect can now draw screen-space stripes

Browse Source 
Added two parameters to DrawStripedRect: fix_stripes_in_screen_space aligns the stripes to screen space. This leads to the stripes of any stripe rect being drawn aligning. Also added inverted, which flips the empty and filled part of the striped rect. This is used to make statRange and findZone stripes interleave, when they overlap.
