Fix #35292: edge slide slow with big image in image editor. Avoid redrawing the
image editor during slide like other operators, instant feedback can be nice but
is not so important here and we don't have notifiers fine grained enough to avoid
full redraws.

Fix #35284: outline name edit textbox did not show properly in some cases. Also
fix issues with its size not scaling with DPI.

Couple fixes for my previous commit:
- In some cases smoke flow could have 1 cell clipped off its sides.
- Forgot to re-enable openmp for emission code.

Fix #35296: particles crash with long object name.

Fix for version patch in recent smoke commit, was using && instead of &.

Cycles: bump node changes to add a Distance input that controls the overall displacement
distance, and an Invert option to invert the bump effect.

Smoke: Add new "Full Sample" option to high resolution smoke panel.

This is hopefully the ultimate solution against smoke blockiness near emitter.

Previously high resolution flow/emitter voxels were generated based on the low resolution ones. So if you had 32 resolution and 4 division high resolution, it still used smoke flow generated from those 32 resolution voxels. Now I introduced a new sampling method called "Full Sample" that generates full resolution flow for for high resolution domain as well.

Read more about it in my blog post: https://www.miikahweb.com/en/blog/2013/05/10/getting-rid-of-smoke-blockiness

Also changed "quick smoke" operator default voxel data interpolation mode to "Cubic B-Spline" to smoothen out it even more.

Set scene frames operator for clip editor.

This operator will set scene's start/end frames to
match clip's start frame and footage duration.

Available in Clip panel in clip editor's toolbox.

Fix for recent bugfix with anisotropic node crash, could do invalid memory access.

Fix #35270: files with numbers higher than 2147483648 or with different numbers
of leading zeros but otherwise the same would show in random order in the file
browser. Selecting an item would change the order of all the items.

Problem was that it was comparing by parsing the number into an int, which has
only limited precision and does not care about the number of leading zeros. Now
do the comparison directly on the string.

Fix #35267: cmd+v, cmd+c on OS X for copy/paste worked in some editors like the 3D
view and text editor but not in the animation editors, node editor and sequencer.

Cycles: add Use Surfaces and Use Hair option to render layers, to disable rendering
of hair and surfaces, similar to blender internal options.

Code cleanup / Cycles:
* Change some more if / else if conditions to switch / case.
* Avoid an unneeded variable casting in phong_ramp closure.

Fix #35278: textures nodes Mix RGB node did not have a Use Alpha option like
the compositing node. Note the shader nodes can't have this because color
sockets there are only RGB, not RGBA.

Fix #35269: compositing setup with only file output node and no composite node
refused to render. It's not possible to actually see the compositing result
in the render result without that but might as well work.

Fix for #35291, Deleting 'Group Output' node in compositor causes Segfault. A group without an output node in compositor would leave the original Node instance in the graph with outgoing connections. This causes trouble because the Node is expected to be a NodeOperation. Now group nodes always get disconnected and if no output node is present will use the default group output values (which is slightly less confusing than using input values from connected nodes).

Fix #35261: double clicking the up arrow in the file browser to go up multiple
directories fast would start drag and drop. Disabled drag on those items now.

use unsigned ints for edgehash

Fix #35282: cycles color ramp set to constant interpolation did not work well.

Fix #35272: cycles GPU crash with anisotropic shader in group node.

Problem was that due to group proxy node the anisotropic node did not detect
early enough that it needs generated texture coordinate data to generate the
tangent. Now the proxy nodes are removed earlier.
