This is part of cleaning the build system for #1906.
The 3d viewer is the last component to not use the action framework, so
we descope the common defines to its canvas. Once the 3d viewer is
converted, we can remove these entirely.
The floor render in raytracing creates interesting shadow effects but
significantly increasing the processing time for renders and has the
side effect of making the bottom of the board very dark if you simply
flip it over. Making this option off by default, we allow power users
to turn it on if needed for their renders while speeding up the default
raytrace and preventing new user confusion.
Given that we compare the dot product (square of length) to s_min_dot,
it means that s_min_dot also needs to be square, or we wind up
converting line segments into circles that are visually distinct from
circles, leading to gaps in polylines.

This corrects an issue with fill segments-per-circle and moves the error

This removes the remaining hard-coded segments counts and replaces them
with the relative error calculation where the segments per arc is

Provide a toolkit-agnostic interface for "busy indicators", which
allows the 3D viewer to show a busy cursor, without the canvases
having to to know how a wxCursore works.
The motivation here is to decouple the 3D renderers from the WX
GUI system, as they can then be used when when there is not an
active window (e.g. for offscreen rendering).
Otherwise, attempting to use a wxBusyCursor without a GUI
available is an instant segfault.
In some linux configurations, the canvas refresh must be posted before

Use the icon scaling logic and call a toolbar rebuild when the

The 3D viewer also uses OpenGL, so it also needs to
adjust based on DPI scale factors.
This patch moves the 3D viewer common config code solely

For now, as EDA_3D_VIEWER is not included in the Kiway settings

Currently, the plugindir in the plugin manager is constructed as

the constructed path ends up as e.g. "/usr/bin/../usr/lib/kicad/...".
For these cases where an absolute path is wanted CMake provides the

bitmaps.h was included in nearly every file in the project due to it

Only about 130 files actually use the XPM definitions defined there, and

rebuilt files for pcbnew alone.
This commit moves the bitmap-related types like BITMAT_DEF out to a new
header, which is still included by base_struct.h, which is less
avoidable for now, it's it's used in the interface.
The icon list is still in bitmaps.h. This has the side effect that's
it's now easier to automatically generate this file.

* Paths defined via pcbnew->Preferences->Configure Paths are now included in
the 3D file browser's drop-down list except for KICAD_PTEMPLATES, KIGITHUB,
KISYSMOD, any paths resembling a URL, and any non-existent paths. When an
absolute path is shortened using one of these path aliases, let's say
'KISYS3DMOD' then the name appears in the pcb file as "${KISYS3DMOD}/blah.wrl".
If a user defines and actual environment variable with the same name, then
that user defined variable will have precedence over the internally defined
variable.
* Paths relative to the current project directory are no longer represented
as "some/path/to/file.wrl". For compatibility with previous KiCad versions
it shall always be stored as ${KIPRJMOD}/some/path/to/file.wrl.
* Various restrictions on alias path values have been removed since the
imposed restrictions could result in corrupted user data as aliases are
silently dropped.
* Overall the patch should improve back-compatibility by providing a ${ENV_VAR}
mechanism for supporting different model root directories and ensuring that
paths relative to KIPRJMOD are expressed in a way that is compatible with
earlier KiCad versions. This allows users more flexibility and the ability
to work in a way that ensures 3D model files can be correctly resolved in
earlier versions of KiCad. Users who do not care about back-compatibility
may prefer to use the newer alias system.
The attached patch fixes a segfault due to a race condition.
If a user starts eeschema with an empty sheet and clicks
the 'cvpcb' button, memory is corrupted and the program
segfaults. The issue appears to arise from multiple threads
accessing the 3D cache and resolver. This patch makes
relevant code thread-safe by using a wxCriticalSection.
(In this case the schematic frame exists, but some members are not initialized as expected, and a crash happens when calling the schematic editor dtor)
Minor other fix: avoid multiple very similar strings to translate in 3d_filename_resolver.cpp
The attached patch ensures the S3D_MASTER class does not cause
a segfault in pcbnew when used from Python scripting.
The issue is due to an "extern KIWAY* TheKiway" which was exposed
to allow S3D_MASTER to use the new resolver to handle 3D filenames.
Unfortunately TheKiway cannot be assigned a value until a window is
created which implements Kiway. The change introduced by this
patch should not alter the behavior of S3D_MASTER compared to
the behavior before the 3D merge.
The extern variable is only there to support S3D_MASTER which in
turn is there to support the current 3DViewer. In the planned software
structure the rather complex S3D_MASTER class is replaced with
a simple struct which only holds the model name and position/
orientation/scale data as stored in the PCB file; since the replacement
does not perform filename resolution there is no need to expose the
Kiway. For example in Mario's branch we removed the extern and
S3D_MASTER class many months ago.
