   4 Subject: [PATCH] gschem: Fix rendering with zoomed out dashed lines. Bug #2876373
   5
   6 Rather than using SCREENabs, use the screen_width function to
   7 determine the on-screen size of dash elements. This clamps the
   8 width at a rendereable size, so cairo does not get tripped into
   9 an error state (and stop drawing other objects on the schematic).
