This implements collisions in the solver of the cloth brush/filter. It
uses the scene colliders as a regular physics simulation.
There are still some parameters (friction, distance to the surface...)
that can be exposed as properties in later patches.
Thanks to Sebastian Parborg for helping me with the implementation.

The panels are rebuilt when a modifier is removed so the button handlers need
to properly finish. By adding a context argument to the panel_delete function
this will happen properly.
This adds a curvature smoothing and intensify details properties to control
the result of the Sharpen Mesh Filter.
Curvature smoothing removes high frequency details from the precalculated
sharpen data, so the filter result has much smoother surfaces and cleaner
sharpen lines;
Intensify details displaces the vertices of creases and valleys in the direction
opposite to its neighbors average, so it intensifies high frequency details
in those areas, producing more noisy and sharp shapes:
Both this properties can be used in combination to achieve a good balance of
high and low frequency details depending on the shape and the desired result.

Previusly it was using the / character, which implies that there is one
deformation mode and and invert deformation mode like in the other two
deformation, but squash and stretch is only one deformation mode and
does not have an invert mode.

The scale deform mode includes rotation by default, so when when scaling
down a part of the models it becomes harder to control as the effect of
the rotation less predictable (similar to using trackball rotation in a
very small radius). This locks the rotation of the segment, so parts of
the model can be scaled down in a more predictable way.

Steps to reproduce were:
* Open File Browser
* Create a new directory
* Cancel renaming with Esc
File selection flags were modified during drawing when the rename button
got removed, but the file name label drawing wasn't checking the
modified state.
The crash is caused by the fact that a NULL Object pointer is passed to
calculate the transform orientation, which has been set to normal.
A check has been include to detect the same.

Use `td->iloc` as the coordinates of the transformed element.
It is more accurate and other transformation modes, such as scale, also
operate on `td->iloc`.
The icons are label buttons. Usually these are not editable and can not
become active. These are draggable ones though (so dragging files can be
dragged by dragging the icon) which creates an exception to this rule.
So hovering the icon would activate its label and when executing the
rename operator via shortcut it wouldn't get exited properly. This broke
the invariant of only allowing a single active button at a time.
Added an assert to check that invariant now.
Letting the code to activate the text button ensure any currently active
button is exited seems sensible.
When disconnecting links for defaulted node group inputs, recurse
into the nested node group nodes, instead of checking the socket
flag. Otherwise the behavior is confusing and differs from Cycles.

Disabled buttons would incorrectly toggle state when a drag toggle
passed over them. This adds a check to prevent a drag toggle on disabled
buttons.

The `rna_Scene_ray_cast()` function tried to find the current depsgraph. To
this end, it required the scene, the view layer, and bmain. Scene has a cache
of per-view-layer depsgraphs, to speed up switching between view layers. This
cache does not contain render depsgraphs, and evaluated view layers also don't
have a depsgraph here.
When a suitable depsgraph cannot be found, a new depsgraph is created. However,
this depsgraph is not evaluated, and has an unexpanded scene pointer with a
`NULL` `view_layer`. Using this then crashes Blender. Also, there was no way
for the code to get the render depsgraph.
The solution is to pass the depsgraph to the `ray_cast()` function, instead of
the view layer. This avoids the depsgraph lookup, and also works correctly when
rendering.
Some add-ons also need updating, which I'll do in the `addons`
repository soon.

This uses the vertices per grid instead of quads to set the limit of
grids per PBVH Node. This should create more leaf nodes in lower
subdivisions levels where the duplicates count is high, producing more
uniform performance across different levels.

There were two issues. First, I made a mistake when I switched from unsigned
to signed integers. Second, two classes with the same name were defined in
separate files. Those classes are in an anonymus namespace now, so that they
don't leak into other files.
ad4928a171 disabled alignment for too many cases. Still try to avoid
aligning many items, to avoid thousands of redundant alignment
calculations. But now we're much more picky adding an sub-row with
alignment.
In Blender 2.90 EEVEE materials were refactored that introduced crashes on Intel
GPUs on Windows. The crash happened in the `local_context_workaround` that temporary
stored compiled materials in a binary form to reload it in the main GL context.
It has been tested that the workaround isn't needed anymore for HD6xx GPUs, but it
is still needed for HD4000.
After several unsuccesfull fixes we came to the conclusion that we could not support
the local context workaround and needed to come with a different workaround. The idea
of this patch is that in these cases there is only a single context that is used for
rendering. Threads that uses these contextes are guarded by a mutex and will block.
Impact on User Level:
* Due to main mutex lock the UI freezes when rendering or baking or feel less snappy
