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.
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).
non-power-of-2 texture support. Note that all I did was pass
the correct width/height into glReadPixels; the result may not
be the same as if non2 textures were enabled.
Deviding two ints together never yields a float... Also, logic of various proxies size corrections was quite broken.
Now we should always get the same (relative) size of text whatever proxy setting/render scale is chosen.
from system/user bookmarks' name if possible.
Volume label on Windows was request from T46083, makes Blender more in line
with 'common' filebrowsing on this OS.
And now, we automatically set name of recent entries from the bookmarks, if path
can be found there, more consistent too from user PoV.
Due to how we find kmi to remove and kmi to add when patching final keymap with user defines,
we could actually end up with same kmi for both, see comments in code for details.
Note that it may be a good idea to make user-defined customizations specific to a given base keymap,
instead of applying them blindly?
Since Blender internal strings are UTF8, changed the initialization
of the string to use initWithUTF8String from default encoding.
Fix worked on OSX 10.5.5.
This is called when modifying an RNA property,
however it can be useful to be able to make a properties
update callback run without having to change it.
IMAGE_OT_save_as assumes that active area is an Image Editor and the logic that should return to image editor after saving didn't run after fullscreen was manually exited.
Note that allocating DM arrays from an editmesh is currently not threadsafe,
however even if were resolved, its more efficient to avoid having to do it in the first place.
We were still using main borwser's FileDirEntryArr to own memory of entries currently in cache.
That was OK for common caching operation, but if was not released when clearing cache!
Nothing dramatic, since that was cleared too, but less often, so e.g. by changing sorting
options you could pile up more and more no-more-used entries there...
Anyway, there is no reason to do that, much more sound and clean to keep everything
cache-related in dedicated FileDirEntryCache struct.
This means main borwser's FileDirEntryArr is now always expected to not store any actual entry!
Note: this can probably be cleaned up a bit more, but would wait after 2.76 for this!
