Fix for the view map construction not taking account of face marks.

Cycles:
* Fix object scaling update issue with interactive rendering + static BVH.
* Fix negative scaling issue with static BVH.
* Fix #29217: excessive fireflies in first sample.

mathutils.geometry.distance_point_to_plane(pt, plane_co, plane_no) - utility function, BLI math version too.

Fix for the Perlin Noise 1D geometry modifier having a noise frequency
relative to the stroke length (i.e., the number of noise displacement
values was the same for strokes of different lengths). This resulted
in very noisy short strokes and much less noisy long strokes. Now the
noise frequency is relative to the distance from the starting point of
a stroke. That is, two strokes of the same length will be distorted
by the same number of noise displacement values, whereas longer strokes
will have more noise displacement values along stroke.

Problem report by JO5EF through the BA Freestyle thread, thank you!

Bugfix [#29212] Select before/after current frame deselects all channels in
graph editor

No need to deselect all channels when doing the select left/right operator,
since we don't replace the selection afterwards with anything useful. This would
be a problem when the "Only Show Selected" option is enabled (as it is by
default), as this results in the curves being worked on disappearing from view.

F-Curves though will still get deselected as a result of the code to deselect
keyframes. Will need to review whether this is still a good idea (original
intention was so that only curves with keyframes selected would remain
selected).

Bugfix [#29125] Motion paths odd behaviour

* Made it impossible to try to calculate/create new motion paths lasting 0
frames (i.e. 250 to 250) since we cannot allocate a zero-length array for these.
Start frame can now be at most end-frame - 1, and end frame at least start frame
+ 1

* If an invalid configuration does occur, warnings/reports will now be issued in
response to this instead of silently failing (as per this bugreport).

Hack-fix for crash-by-assertion on mingw builds on startup if the CUDA driver on
the computer is too old (and probably can't be upgraded to a version that does)
to support the cuDriverGetVersion method.

Cycles: more linux build system tweaks, attempting to avoid using boost
system libraries by default if we have a lib/ directory.

Added to the Parameter Editor mode new stroke geometry modifier `Blueprint'
that produces a blueprint using circular, elliptic, and square contour strokes.
Related changes and bug fixes were made as follows:

* The randomness in radius and center has been transformed into optional
parameters of the pyBluePrintCirclesShader and pyBluePrintEllipsesShader.
Also a new optional parameter to control the randomness of backbone
stretching has been added to the pyBluePrintSquaresShader.

* A bug in the pyBluePrintSquaresShader that invisible stroke vertices at
corners of rectangular contour strokes were not properly drawn. The problem
was due to the changes of the / operator between Python 2.x to 3.x. Even
when the two operands of the division operator are integers, Python 3.x
gives a floating-point number when the quotient is not an integer. The fix
was just to replace the / operator by the // operator for integer division.

* An unpleasant discontinuity in circular and elliptical contour strokes
was fixed.

* The length parameter of the Backbone Stretcher geometry modifier has been
renamed to `backbone_length' in line with the parameter of the same name in
the pyBluePrintSquaresShader.

Cycles: fix wrong openimageio path for lib/ directory.

Fix #29207: cancelling volume precache at high resolution was too slow, added
more test_break calls.

CMake/Scons: automatically use ffmpeg, boost and openimageio from the svn lib/
directory if available, which should make building with ffmpeg and cycles easier.

If this folder is not available or another path is specified in user-config.py
or CMakeCache.txt, this should have no effect. Wiki build instructions now show
how to use these.

correct indentation and some whitespace edits (no functional changes)

quiet -Wdouble-promotion warnings

Fix #29220 & #29221: missing cycles updates when switching scenes.

bmesh compiles again after dynamic paint merge

Dynamic Paint:
* Renamed "Sharp" proximity falloff to "Constant".
* Added a new "Negate Volume" option for "Volume + Proximity" brush.
* Possible fix for random particle clipping errors.
