jean-pierre charras 407301a28c Fix issue in cairo_gal when drawing a 360 deg arc (in fact a circle). It was due to a angle normalization between -360 and 360 degrees. So, in arcs, if the start angle and end angle diff is n*360 deg, this normalization gives start angle = end angle. The fix forces end angle = start angle+360deg in this case.

Tomasz Włostowski bbee30671a gal: pixel alignment hacks, works for Retina display too now. 
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

jean-pierre charras 388397f97d Protect TesselatePolygon() against degenerated polygons (less than 3 corners) to avoid crashes. 
Use TesselatePolygon() to draw polygons in Gerbview instead of GLU tesselation, much slower.
Add helper methods in GAL to know if the current GAL engine is Cairo, OpenGL or something else,
useful to optimize drawing code.

jean-pierre charras ffe4b745dd Opengl gal: Fix bug: segments with 0 length are not drawn. However the are equivalent to circles. 
Using 0 length segments happen with oval pads having the same X and Y size, and in some other cases.
