It was re-enabled by commit cbc3bfbf.
The current code to handle cached bitmaps is no longer compatible with the
current code.
Many cached items are created because a lot of clones are used to manage bitmap images.
Cached items are never cleaned, so a lot of memory is never freed after
using these temporary clones
And caching items do not significantly speedup drawings.
Tested on msys2 which is the only place it would have been buggy
CMake seems to share the gdiplus linkage with the other dependencies automatically now
Also adjusts metrics to better match stroke font.
Also removes text-halo highlighting as it's too expensive to re-render
when the zoom changes.

On wx3.0, the HTML format #RRGGBBAA cannot handle the alpha channel.
Instead, we route this through a COLOR4D routine when we need to use
these colors

Improves rendering performance, esp. for large designs by:
- using a separate glDrawArrays calls() for large buffers of contiguous vertices (e.g. large zone fills)
- pooling smaller items into a small-sized index buffer held in system RAM (has to be DMAed to the GPU by the driver anyway)
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

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).

curl.h has constraints on Windows (because it includes winsocks2.h) and must be
included before any wxxxx.h.
Because only very few files need curl.h, kicad_curl.h is included only in these files
Fix the valgrind warning from the use of an uninitialized
member variable by setting the DEFAULT value for
m_currentNativeCursor in the constructors member initializer list.
This fixes the following warning caused by the SetNativeCursorStyle
method call later on the constructor.

Error can be reproduced and checked from the log.txt
by launching kicad with valgrind command
"valgrind --leak-check=full kicad > log.txt 2>&1"
and then launching the footprint editor from the kicad main dialog.

The max-char-width impl was buggy and never applied to PCBNew anyway.
Plus the stroke font has a max-char-width of 2.8 time the space width,
so it made for really wide tab spacing.
Also fixes a bug where the Scintilla editors weren't getting a
monospace font on Mac. (This bug may also exist on the other
platforms, but each would need its own fix.)
Also moves more of the Scintalla customizations to SCINTILLA_TRICKS
where they can be shared.

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)
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.
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).
This was leaking windows headers and partial wx headers to 1084 compilation units......
This also means math/util.h is leaking to 1084 compilation units which seems a bit high too.
Initialized COLOR4D takes an EDA_COLOR_T enum but then referenced it as
an index to the color table. This uses the enum as comparison against
the table-stored enum.
Adds standard orange to picker swatches
VIEW::GetBoundary() returns the entire view area, not the visible area.
Surprisingly, we had no API for this, so I added one.
Also, changed the dragger behavior to toggle between optimizing just the
modified area and optimizing the visible area, i.e. we will now never
optimize off-screen portions of the dragged track.
The native cursor must be set on the GAL canvas wx object,
not its frame (otherwise on GTK the cursor is only set
when we get a request for it from the WM and not immediately).

Vertex memory allocation uses malloc and realloc without checking the
result. Throw exceptions that can be caught in the DoRepaint() method
in EDA_DRAW_PANEL_GAL when malloc and realloc return a null pointer.
We had been using each 4th column of spaces. But we needed an absolute
spacing rather than relative to the existing text to match spacing
between the input text box and our stroke font
wxWidgets 3.1.5+ on Linux will compile with the Wayland EGL
canvas as the backend instead of the X11 backend. This requires a
version of GLEW compiled with the proper EGL defines and a different
header/code for certain parts that are X11 GLEW specific.
This introduces an in-tree version of GLEW that will be built with the
GLEW_EGL flag then statically linked into the KiCad executables when
EGL support is needed.
Correcting the error is more trouble than it is worth, and anyway
might not be corrected exactly the same way plotting/filling/DRC
is corrected anyway.
Use a segment count multiple of 2, because we have a control point on the
middle of the arc, and the look is better if it is on a segment junction
because there is no arc to segment approx error
The radius correction does not fix correctly approximation errors,
and creates serious issues for thin arcs:
- control point outside the arc
- HitTest active area outside the arc shown on screen
- Cairo and opengl gives different arc positions.
- the formula used in radius correction is probably incorrect.
The OpenGL missing segments (when small) are due to rounding in larger
coordinates. The GAL shader uses floats to represent int32 values for
position and distance. Thus, at larger coordinates, the smaller integer
values cannot be represented accurately. This tests for the rounding
error and, if it exists, draws a plain circle instead

You can now enable and disable snap to grid when drawing/editing across
all apps. You can also tie snap to grid to the visibility of the grid
to allow rapid enable/disable via grid display.
Cairo Polyline and Polygon draw functions share a common routine. While
Polygons must have 3 points to allow triangulation, a polyline (like our
text) need only have 2
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
(https://gitlab.com/kicad/code/kicad/-/merge_requests/365) for
identifying the issue.
The use of printf, wxLogDebug, and std::err/std::out causes excessive
debugging output which makes finding specific debugging messages more
difficult than it needs to be.
There is still some debugging output in test code that really needs to
be moved into a unit test.
Add debugging output section to the coding policy regarding debugging
output.
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.
Fixes https://gitlab.com/kicad/code/kicad/issues/5089
On platforms with limited framebuffer attachments, like GC7000L
driven by the open source etnaviv driver, we can still use
GPU acceleration by drawing directly to the main buffer.
EDA_DRAW_PANEL_GAL::onPaint checks if an overlay target is
available in the GAL, and if not, redraws the whole view if the
overlay target should be dirty.
Clearing of the overlay target is a no-op if there is no overlay
buffer.

When drawing segments that are smaller than the segment width, OpenGL
did not use realistic values, leading to hidden, small tracks. Instead,
we set the track to only draw a segment when the length is at least 1
radius long (so that we can see the full semi-circle at the track end)
