Workaround for C nodes: In order to make registerable RNA methods of the standard C nodes (e.g. poll or draw_buttons) available in python scripts, they need a specialized Node subtype (called NodeInternal). This is necessary because bpy omits any registerable functions of RNA types in the generated python classes, relying instead on using the supposed native implementation in a registered python class. Since the standard shader/compositor/texture nodes in Blender are not registered but directly created in makesrna they lack all registerable function in the associated python types. The NodeInternal RNA subtype replaces the registerable functions of the base Node type to solve this issue.

Extended the draw callback API for node sockets with an explicit text parameter, instead of always using the sock->name string. This can be useful for drawing the socket values separate from the label, e.g. in the node view template.

Change to socket draw functions: instead of always only drawing the socket label for connected sockets, leave this check up to the socket draw function itself. This allows future socket types to draw buttons or other info in all cases and handle connected/unconnected state more flexibly.

The drawinputfunc/drawoutputfunc callbacks in bNodeType are pretty much empty wrappers now and should be removed at some point. This per-node differentiation should rather be implemented as a specialized socket type if necessary. The only use case for this feature that remains is the file output node in compositor, which displays shortened file format info for each socket.

more optimal method of calculating the normal for the solidify modifier.
When adding 2 unit length vectors, the length can be used to calculate the angle.

Mask modifier for sequences

This modifier uses a mask set in the modifier settings
and multiplies strip by it. Alpha channel will also be
multiplied by mask, which makes it easy to mask some
objects on footage and alpha-over them in sequencer.

Actually, this modifier sets alpha for byte strips
directly (since byte is always straight alpha) and
multiplies float buffer by mask (flaots are premulled)
so in both cases masked strip could be easy alpha-overed
without any artifacts.

It uses own structure with only SequenceModifierData
property in to preserve both forward and backwards
compatibilities (using new structure ensures modifier
will be ignored on load in older blenders, the same
happens for mesh modifiers actually).

Request from Pablo Vazquez.

Fix for #35253, Cannot animate X, Y, Z values in nodes with vector sub-menu. The "component menu" template used for these socket buttons opens a popup, but this ui function does not support RNA info directly. Setting the uiBut rna pointer directly solves it.

code cleanup: dissolve - use iterator macros, remove unused function.

mesh dissolve vertices: option to split off corners of surrounding faces, makes the result more localized to the area around the vertex.

split dissolve into 3 different operators (face/edge/vert).

Fix #35219: blender internal auto ray bias to avoid the terminator shadow
problem was giving light flickering on a mesh with animated hair strands.

Now strands are not used to compute this auto bias excluded from this, from
tests it does not seem to be helpful for hair and only gives issues.

Fix #35240: command line -t number of threads option did not work for cycles.
Now it works for blender internal, cycles and other multithreading code in
Blender in both background and UI mode.

Fix #35246: cycles has no simple way to combine bump and normal mapping. Now
the Bump node has a Normal input, so you can chain it after a Normal Map node.
Note that normal mapping always has to be done first because it is tied to the
particular mesh surface and tangents.

fix for recent commit, WITH_GUARDEDALLOC wasn't enabled for makesrna, makesdna.

Fix #35093: New Basis shape key doesn't act as Basis

Made it so Move Shape Key ensures first key is a refkey,
so now it's possible to change basis key from the interface.

It's still needed to manually teak key's relative_key,
not sure whether there's a reliable automated way to tweak
this value when bassi key is changing.

Fix #35252: Crash with the node placed partially behind the screen

Issue was caused by negative maximal possible text width happening
in label clipping.

Solved by clamping width to 0 if it's negative.

fix [#30862] "Lock" and "Box" Quad View options won't stay put when toggling

add in asserts when rv3d->viewmatob, rv3d->persmatob are not initialized.

This is often hard to spot since in many cases it works correctly even
when not initialized but may still fail in other situations.

code cleanup: ui_but_is_rna_undo --> ui_is_but_rna_undo (ui_is_but_*** is used elsewhere)

minor speedup for bmesh - add CustomData_bmesh_free_block_data(), use
when the block would be immediately allocated again.

code cleanup: remove ShapeActionActuator, they are now versioned out.
