Math Lib: rename fill_*, to copy_*

matching convention for fixed length api, eg: copy_v3_fl

Cleanup: function arg wrapping

Cleanup: rip tool

Cycles: Use curve approximation for blackbody instead of lookup table

Now we calculate color in range 800..12000 using an approximation a/x+bx+c for R and G and ((at + b)t + c)t + d) for B.
Max absolute error for RGB for non-lut function is less than 0.0001, which is enough to get the same 8 bit/channel color as for OSL with a noticeable performance difference.
However there is a slight visible difference between previous non-OSL implementation because of lookup table interpolation and offset-by-one mistake.
The previous implementation gave black color outside of soft range (t > 12000), now it gives the same color as for 12000.

Also blackbody node without input connected is being converted to value input at shader compile time.

BMesh: improve rip tool /w mon-manifold verts

Can now rip from multiple fans (mixed single faces or larger regions)

Also add BM_vert_is_manifold_region which only checks if a vert has disconnected fans.

Cleanup: style & const's

Cleanup: wrapped function indentation

Cleanup: deduplicate code.

FileBrowser had its own 'shorten_string' func, when we have a full fledge one in interface_widget code...

Revert "Different drawing for object centers."

This reverts commit 5a8629c0d7da6cfb4b696f1787111c9492e03aba.

It does not really work that well since objects can draw in front of
selection circles now.

UI: location/scale were snapping to 10s

In practice this isn't useful (for scale especially).

For float buttons with a very large range, don't attempt to match the snap to the range.

UI: button snap (ctrl) was rounding down

Fix T44503 full sample does not display any preview any more.

The fix exposes another error not fixed in this commit, escaping the
render will not flush the full sample render result correctly.

Fix eyedropper with quad-view

Fix T44592: Zero scale on an axis, zeros all

Follow up to previous commit, remove depth of field from UI in
wireframe/boundbox mode.

Fix T44594 disable depth of field in wireframe/bounding box modes. We
don't supply depth information in those modes so supporting the effects
does not really make sense

Fixed comment.

Cycles: Fix copy / paste mistake in XML reader.

Fix possible crash with datatransfer operator when source object was hidden.

Mismatch in poll and exec funcs when getting active (source) object...

Different drawing for object centers.

Code here did depth test always and depth range 0.0.

There is no real reason for object centers to write and get tested
against depth buffer in this case, just disable the depth test instead
;)

Helps with blurry object centers in depth of field mode too (centers
wrote depth 0 and were always blurry)
