david-beinder 2b4564571c GAL: Tune SMAA to have a conservative and aggressive mode
Fixes https://gitlab.com/kicad/code/kicad/-/issues/8522
Conservative makes SMAA usable in Eeschema through weaker AA.
Aggressive reduces some artifacts compared to the High preset.
Restores the unused Ultra preset in the shader source to its original state.

Hajo Nils Krabbenhöft 937f502158 Improve accelerated supersampling 2x antialiasing
Avoid fractional pixel offsets by forcing integer division of m_screenSize.
Shift rounded lookAtPoint onto OpenGL pixel center to ensure consistent rounding to int.
The pixel 0..1 @ 1x needs to fill the area 0..2 @ 2x so its center moves by 0.5 * (pixel size @ 1x).

Urja Rannikko aa7ab46a06 GAL: Round the incoming mode parameter in fragment shader
This fixes some letters being randomly boxes and some circles
being randomly triangles on the Mali T760.

Urja Rannikko 65ceeebc71 GAL: Remove dead code regarding SHADER_LINE_B in the fragment shader
The only test for it was only called from a function
that's called if the mode is SHADER_LINE_A, not B.

Jon Evans a94a81b9a8 GAL: Handle text opacity in OpenGL
Vertex alpha was being dropped in the font shader

Seth Hillbrand db0523626c GAL: Deal with thick circles
Both Cairo and OpenGL had issues (different, though) with circles that are
thicker in line width than they have radius.  This corrects the OpenGL
implementation (radius is calculated to the outer edge) as well as Cairo
(line width needs to be clamped to twice the radius)

Seth Hillbrand f1a60832e0 opengl: Handle stroked semi-circles
And filled but we don't use those yet.  No pixel-alignment needed for
stroked semi-circles (I think) as we set the pixel width to be 1
regardless of the zoom level.

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
