Seth Hillbrand 52bbfb9109 Remove dependency of dot size on linear mils
Changes a dot to be a square pixel (linewidth x linewidth).  This allows
the removal of IU dependencies and ensures that a dot is always visible
on screen.  Also makes sure that cairo is setting the current linewidth
during its stroke routines

jean-pierre charras 36048fa436 OPENGL_GAL::DrawArcSegment(): use a better number of segm to approximate the arc.
Previously, the count of segments used a magic number optimized for Pcbnew.
This is not good, and does not work well on Gerbview.
The count uses now a max error acceptable is approximation (5 microns in Gerbview and Pcbnew).

Mike Williams 30987cebfe Gerbview: fix cairo negative items and implement real differential mode
Layers with negative objects need to be drawn in a subsurface before
copying so they don't _CLEAR the draw items below them when a negative
object is drawn.

Differential layers are basically the same thing only they use a
different copying operation onto the layers below.

Seth Hillbrand ea283625a7 Further simplification of AA regime
Reduce each (Accel & Fallback) to 3 options: Off, Fast, Good.  Fast AA
in accelerated canvas uses SMAA with tweaks suggested by David Beinder.
Good AA is super-sampled x2.

Cairo is similarly reduced to Off, Fast, Good, which map to the Cairo
options themselves.  Best is removed as it mostly affects text rendering
and not line drawing (as our text is)

Ian McInerney 5684708b22 Remove shadowing linewidth member from the Cairo GAL
The base GAL has the linewidth property already, and its
accessor will only return the base version. This was causing
problems with the Cairo printing GAL, since that setter wasn't
using the base class version. Also, this removes the print-specific
setter, since the actual setting of line width shouldn't be done
there and is instead done where the drawing happens.

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.

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.
