Epsilon was quite arbitrary for GPU, replaced with checking for zero-sized faces.
It should solve both original report and the new one. After the release we can check
why GPU doesn't produce accurate math here and go to the root of the issue.
The user interface was ignoring the precision step size for degrees,
making all rotation inputs drag by a 100th of a degree.
Now use a 10th of a degree instead.
SCons didn't pass `-DWITH_AUDASPACE` to the compiler, so it skipped the
instantiation of the "aud" Python module. This caused a crash of the BGE,
which did get the `-DWITH_AUDASPACE` directive, and expected that module
to exist.

As of this release we're able to navigate with the keyboard in the filebrowsing area. The button caption is changing to an appropriate string whenever a new entry is selected. In @Severins original code a different method was used to determine if a directory was choosen or not, but this got lost while merging the filebrowser rework.
Thanks to @mont29 for review!
For now simply show warning in the interface and fallback to regular subsurf
code. Supporting OpenSubdiv in edit mode in possible but not high priority
currently.
The issue was caused by some special tricks needed to compile OpenSubdiv shader
which was using stupid check whether geometry shader is used or not.
Now made it more explicit call whether special OpenSubdiv trickery is needed or
not.
Its not ideal solution, but it's not really easy to do a proper solution for
this, because while we can do half of the work with if-defs in the shader code
but we'll still need to somewhat define layout of the input blocks which isn't
really doable with current shader version we're using.
Disable Intel cards for until we'll go to the root of the issue of the crash.
This will take a bit, so being so close to the release we go safe and disable
unstable GPU, so blender at least doesn't crash.
This could be bypassed by setting OPENSUBDIV_ALLOW_INTEL environment variable.
support is missing.
Supporting those (really) old GPUs requires us to make shaders more
expensive by converting between real and scaled coordinates and be wary
of such conversion caveats when handling uv coordinates in shaders. Not
worth the cost for supporting hardware that old.
Also they did not work when using blender -R from
command line in 64-bit systems.
Issue was checking for wrong define which would
cause code to detect if the blender executable
functions under 32 bit emulation.
For 64bit executables this is false, leading
blender to believe we are operating under a 32bit
system, and registration would try to register
the 32bit thumbnailer.
This 32 bit dll is (correctly) missing for local
installs and from the new installer, thus no thumbnails.
Using the global scheduler here is not a really good idea - `filelist_cache_previewf()` is not a short task
that run once, but it's a loop that keeps cheking for work in a TODO queue. This means it won't quickly allow other tasks
to start, so it should not be in the global scheduler.
In fact, asynchronous tasks (that is, tasks that will live for quite a bit of time, and often sleep a lot) should never use
global scheduler, they would steal computing resources from heavy-duty, short-time living ones - and possibly even completely
stall threaded tasks (if all worker threads are executing long-life tasks...).
We could probably even completely bypass the scheduler/task thing here (and directly use threads), but it does not have
that much of an over-head, and still offers easy handling of threading stuff...
Added a helper that ensures a bbox has some non-NULL dimension along all its axes.
Also, fixed some (rather unlikely) NULL dereference cases (though it should not in this context,
`BKE_object_boundbox_get()` can return NULL).
