Math Lib: Add mat3_from_axis_conversion_single

Single axis version of mat3_from_axis_conversion,
when the second axis isn't important (orienting an arrow for eg).

Fix T51756: Fix crash when transforming vertices in edit mode

The issue was caused by under-allocation of UV islands calculation.

Fix T51750: Group selection broken

Proper way, no base is involved.

Fix T51648: Inconsistent edge collapse point depending on orientation

Edge collapse was using bounding box center as the point to collapse to.
When collapsing multiple adjacent edges together, this caused
inconsistencies in placement of the collapsed point, depending on the
orientation of the edges in relation to the space axis.

This makes edge collapse use the mean point instead.

install_depsh: update OpenCollada to 1.6.51, and OIIO to 1.7.15

Revert "Fix T51750: Group selection broken"

Fix for fix for bplayer (c) :/

Cycles Denoising: Merge outlier heuristic and confidence interval test

The previous outlier heuristic only checked whether the pixel is more than
twice as bright compared to the 75% quantile of the 5x5 neighborhood.
While this detected fireflies robustly, it also incorrectly marked a lot of
legitimate small highlights as outliers and filtered them away.

This commit adds an additional condition for marking a pixel as a firefly:
In addition to being above the reference brightness, the lower end of the
3-sigma confidence interval has to be below it.
Since the lower end approximates how low the true value of the pixel might be,
this test separates pixels that are supposed to be very bright from pixels that
are very bright due to random fireflies.

Also, since there is now a reliable outlier filter as a preprocessing step,
the additional confidence interval test in the reconstruction kernel is no
longer needed.

Fix compilation issue

Probe: Add influence display and rework UI.

Probes: Add more parameters.

Add Min Max for box, and distance for sphere falloff.
Same for parallax.
Add clip distances.

Eevee: First commit of Probe support.

Draw Manager: Add request redraw method.

This is extremly hacky and against notifier design. This must be revisited later.
We might want to mimic external renderer way of requesting redraw.

Draw Manager: Add support for temporary matrix override.

This allow to specify custom matrices for certain specific passes.

Draw Manager, GPUTexture: Add support for binding individual cubeface to framebuffer.

Probe: Add panel and "Add-menu" items.

Also revisits defaults.

Probe: Add initial visualisation

Probe: fix some missing bits / errors in RNA ...
