gal: pixel alignment for Cairo. gal: pixel alignment for OpenGL Cleanup of pixel alignment patches gal/opengl: more pixel alignment patches: - works on Retina displays now - pixel alignment for circles - correct 1-pixel strokes - fixed unfinished 1-pixel line ends GAL: Restore antialiasing options in Cairo GAL: Fix arc drawing Removes DrawArcSegment, which drew arcs whose edge was optionally stroked (a feature that we did not use). Fixes Cairo arc drawing issue where arcs were not visible in pcbnew. gal: further cleanup gal: removed unused shader parameter
