Seth Hillbrand 80af7b3158 Fix GAL check to account for shared function
Cairo Polyline and Polygon draw functions share a common routine.  While

Seth Hillbrand 7fc222db98 GAL: Check that polygons have at least 3 points
This resolves a crash when passing an empty polygon and alerts debug
users to possible generation cases when bad polygons are created.

Thanks for Frans Zellman

identifying the issue.

jean-pierre charras 63eb552e0a 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.

John Beard 15bba27406 BITMAP_BASE: Add const image data accessor
This allows a const BITMAP_BASE to expose const image
data. This is currently done with const_casts, which is
"OK", only as long as the source image is not declared
const, in which case it's undefined behaviour.

Also immediately dereference the pointer to a reference
if it's not checked to make the non-null requirements
explicit at the point of access.

(line width needs to be clamped to twice the radius)

Seth Hillbrand 2305c5458e cairo: Prevent arch shaking in pcbnew
Arc pixel adjustment needs to be limited to +/-1 pixel.  But making this
adjustment to nearby points and then using the projection to correct the
center point accumulates errors that are large for angles near 0 and
near 360.  This is a compromise that aligns _most_ arcs and provides
stable generation for all angles.

Seth Hillbrand e8333633fe GAL: Add antialiasing options to Cairo
Cairo supports antialiasing when rendering but can be slow when set to
sub-pixel mode.  This bumps the minimum version of Cairo to 1.12
(available in 14.04 LTS as well as mingw) to support three antialias
settings (fast, good, best) that offer speed/appearance tradeoffs.

This can provide a higher-quality eeschema render as it works on a
per-element basis as opposed to the OpenGL per-screen antialias.

Display GALs had an incorrect world unit value set. Now the world unit

so scaling worked differently for display and print GALs.
