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
* Renames /qa/common to /qa/qa_utils, as it is not to do with /common
* Renames /qa/geometry to /qa/common
* Put existing geometry tests into a subdirectory of /qa/common, to
echo the layout of the main tree.
The intention is to provide a place to put tests of other libcommon
code in the /qa/common suite.
