The original intention from [0] was to force background-mode when built
WITH_HEADLESS or WITH_PYTHON_MODULE, with the else clause setting the
signal handler for Ctrl-C. Since WITH_PYTHON_MODULE now disables all
signal handlers this check no longer makes sense.

* Fixed crash in debug draw code. Apparently this is
only used by PBVH draw?
* Debug draw code can now be forcibly enabled in release
mode (i.e. RelWithDebugInfo) by uncommenting a commented
out #define.
* Fixed colors in debug draw mode.
* PBVH node boxes in debug mode now flash a different color
when they are updated.
SCULPT_undo_push_begin no longer takes an explicit
name. Instead it takes a wmOperator pointer and uses
op->type->name for the name. This is necassary for
the redo panel to work and should fix the entire class
of bugs related to misspelled undo push names.
Cases where the calling operator is not registered
may use SCULPT_undo_push_begin_ex if desired; it
takes a name string as before.
This new implementation does all downsampling in a single compute shader
dispatch, removing a lot of complexity from the previous recursive
downsampling.
This is heavilly inspired by the Single-Pass-Downsampler from GPUOpen:
https://github.com/GPUOpen-Effects/FidelityFX-SPD
However I do not implement all the optimization bits as they require
vulkan (GL_KHR_shader_subgroup) and is not as versatile (it is only
for HiZ).
Timers inside renderdoc report ~0.4ms of saving on a 2048*1024 render for
the whole downsampling. Note that the previous implementation only
processed 6 mips where the new one processes 8 mips.
```
EEVEE ~1.0ms
EEVEE-Next ~0.6ms
```
Padding has been bumped to be of 128px for processing 8 mips.
A new debug option has been added (debug value 2) to validate the HiZ.
With this patch true headless OpenGL rendering is now possible on Linux.
It changes the logic of the WITH_HEADLESS build flag.
The headless backend is now always available with regular builds and
Blender will try to fall back to it if it fails to initialize other
backends while in background mode.
The headless backend only works on Linux as EGL is not used on Mac or Windows.
libepoxy does support windows and mac, so this can perhaps be remedied in the future.

This cleans up the OpenGL build flags and linking.
It additionally also removes some dead code.
One of these dead code paths is WITH_X11_ALPHA which actually never was
active even with the build flag on. The call to use this was never
called because the default initializer for GHOST was set to have it off
per default. Nothing called this function with a boolean value to enable it.
These cleanups are needed to support true headless OpenGL rendering.
Without these cleanups libepoxy will fail to load the correct OpenGL
Libraries as we have already linked them to the blender binary.

With libepoxy we can choose between EGL and GLX at runtime, as well as
dynamically open EGL and GLX libraries without linking to them.
This will make it possible to build with Wayland, EGL, GLVND support while
still running on systems that only have X11, GLX and libGL. It also paves
the way for headless rendering through EGL.
libepoxy is a new library dependency, and is included in the precompiled
libraries. GLEW is no longer a dependency, and WITH_SYSTEM_GLEW was removed.

When dropping file to sequencer timeline, coordinates for strip position
and overlap handling are used even if not set.
Reset internal state in on_drag_start callback and set is_modal
variable only if coordinates are updated. This way when dragging file
from external file browser, strip is added at current frame as before
modal operator was implemented.

Ensure render passes are allocated in the result prior to writing them.
Alternative could be to not write empty passes, but that is kind of
different from perspective of s one who reads the file.

Need to update relations when modifiers are added or removed
since those create nodes in the dependency graph.
Added an assert statement to point at possible culprit so
that issues can be fixed more quickly.
The status bar keymap items still don't get translated because the
TIP_ translation introduced by rBe1974ae30e46 uses the wrong context:
it uses the default context, while the extraction introduced in
rB630b961f234e uses ID_WINDOWMANAGER.

This is not dynamic: it only happens when the dir is added to the
list--automatically for recent files, and by the user for bookmarks.
Entries can then be manually renamed like other dirs. They will
keep the same name if the language is changed afterwards.

Compared to the previous implementation this has a limit of 65536 lights
per scene. Lights exceeding this limit will be ignored.
This also introduce fine grained GPU light culling, making rendering
many lights in a scene more efficient as long they don't overlap much.
Compatible light panels have been unhidden.
Note: This commit does not include surface evaluation, only light culling.
These are meant to provide easy shape and AABB operation for culling.
They are currently incomplete but can be extended as one see fits.
The `common_debug_shape_lib.glsl` contains helper to draw thoses shapes.
Adjust static font details so that we can properly display Arabic
contextual letter forms. And so that alphabetical ligatures are loaded

Own Code.
In this case the array allocation would allocate an array of size zero.
This would then later lead to out of bounds memory reads.
Now the code will skip zero length allocations.
As the surface normal is calculated along with the coordinates, the
surface depth was always being used when surface orientation was set.
Therefore, even calculated, ignore the surface depth when it is not
required.
Also promote an optimization when neither orientation nor depth is required.
