f0db870822 added support for tree-views to remember state, but only to
remember their custom height for the start. This change makes the scroll
offset be remembered too.
Not remembering the scroll offset can be very annoying in some cases,
e.g. when working with bone collections and changing the active tab in
the properties editor often. In realistic, non-trivial bone collection
set ups this can lead to a lot of repeated scrolling.
To align better with the pixel and reduce the samples needed.
The paper was using gamma because the jacobian |d_gamma/d_h| approaches
infinity at the boundaries, but it seems that clamping at 0.999 is
enough for numerical stability.
In practice I did not notice a change in the noise level, but it
simplifies the range computation and renders faster due to reduced
sample amount.

Enables building of a Cubin for GPUs based on Blackwell architecture
if CUDA toolkit version 12.8 or higher is installed.
Only added sm_120 to the default set, since it is the one relevant for
consumer GPUs (RTX 5090 etc.) that are generally used with Blender.

The usual issue of non-trivial C++ data being allocated with C-style
`alloc` code.
Also added more default initializers to some generic RNA-related structs
that embded some `PointerRNA` members.
The removal of the loose uniform made the shader not compile.
This patch adds a new define for these type of shaders and add
back the loose uniform.
Note that these shaders might no longer work on Metal as
the source is not parsed anymore.

The compositor crashes when the active viewer layers is deleted and
replaced by a new layer. That's because the depsgraph of the compositor
still references the old view layer. To fix this, we need to update the
view layer of the compositor if it changed since it was last created.

The symmetric separate blur operation in the compositor is two times
slower in 4.4 compared to 4.3. On Linux, this only happens when Blender
is compiled with GCC, because Clang inlines a small function that GCC
doesn't.
To fix this, we specialize an if statement using templates to help GCC
inline the function. This results in a 3.5 times faster execution.

When filtering events by labels and not passing an `event_type`, events
that don't pass the label check would be returned. See #134331.
Mistake in 5de40adc9e.
Also clarify behavior in function comment.
If there's no material in the Grease Pencil object, exporting those
strokes will cause crash because the SVG exporter didn't handle the
case for when there's no material. Now uses black stroke when material
is `nullptr`.

The use of `GeometryDeformation` is incorrect for computing the bounds:
It contains _evaluated_ positions for the _original_ points, but does not
match the size of evaluated geometry after constructive modifiers like
Line-Art. For the bounds the evaluated positions should be used as-is.

This patch refactors the ShaderNode class to be a concrete class that
is implemented in terms of the node type gpu_fn. This is done to make it
easier to reuse existing nodes in other parts of Blender.

Natural drawing speed fails for strokes that are pasted or duplicated.
This is due to the `init_time` attribute being transferred from previous stroke
to the new, resulted in the same values. This further calculates wrong
`build_factor` inside `get_factor_from_draw_speed`. To further explain
this, `gap_delta_time = -prev_end_time` which evaluates `start_time=0` for
the duplicated curve. To avoid this situation, make sure `gap_delta_time`
is positive. So `start_time` will be > 0.

`mouse_over_key_get_from_strip` doubled the hotspot for start and end
fake keys, but this was not reflected in the other use case of
`RETIME_KEY_MOUSEOVER_THRESHOLD`. Fix and add a comment for
documentation.
OpenCollada used to rely on PCRE (a Perl Regexp library). Since
switching to Aras' OpenCollada fork (#122270), the library is no
longer needed, but is still required as a dependency.
This patch cleans this up by completely removing it from our build
system and linux system package installation script. This also lets
us remove it from our pre-compiled library platform repos, making the
process of recompiling our libraries from scratch easier as it wasn't
compiled by our dependency builder anymore.

As noted in #134241 this modal poll function cannot return false on an
item because there is a conflict in the way the operation is started
versus how it is set to cancel. Doing so also stops the escape key from
canceling the operator.

This commit adds a test for the outputs of the object info node.
This includes testing on meshes, and testing the random output on
lights, using area lights placed behind glass.
Tests were added for lights as they take a different code path.
And the glass was added so the lights will be visible to the camera in
the EEVEE render engine so this test can be reused when/if EEVEE gets
light nodes support.
