MetaBall: optimize memory allocation for meta-ball tessellation

Double the allocation size when the limit is reached instead of
increasing by a fixed number.

Also re-allocate to the exact size once complete instead of over
allocating. This gives a minor speedup in my tests ~19% faster
tessellation for ~1million faces.

Fix meta-ball bound-box calculation reading past buffer bounds

This broke "test_undo.view3d_multi_mode_select" test in
"lib/tests/ui_simulate" and is likely exposed by recent changes to
bounding box calculation.

The missing check for DL_INDEX4 dates back to code from 2002 which
intended to check this but was checking for DL_INDEX3 twice
which got removed as part of a cleaned up.

This could be hidden from memory checking tools as meta-balls
over-allocate vertex arrays.

Fix compile errors on windows.

Cleanup: Use pixel in stead of texels in naming.

Images: 1,2,3 channel support for transform function.

Added support for 1, 2, 3 float channel source images. Destination
images must still be 4 channels.

Documented IMB transform.

Added documentation.

Sanitized node editor backdrop matrix.

LineArt: Ortho tolerancec effective for perspective.

In perspective cameras, there will still be certain rare cases where
the camera needs to be rotated ever so slightly, so make that option effective.

Fix T94082: Curve to point empty evaluated NURBS crash

This is basically the same as rBee4ed99866fbb7ab04, the fix is
simply to check if the spline has evaluated points when deciding
the offsets into the result points array.

Sculpt-dev: fix BKE_brush_add

* BKE_brush_add now calls BKE_brush_sculpt_reset if
ob_mode has OB_MODE_SCULPT set. This should hopefully
eliminate a whole class of bugs I've been chasing.

Fix possible use-after-free on error handling during VR view drawing

Whenever an exception happens in VR session code, we cancel the entire
session. Alongside that, we removed the "surface" item used to draw into
an offscreen context. This would mess up the iterator of the surface
draw loop.

* Added option to ignore UVs for sculpt

* Tweaked sculpt header a bit.

Fix possible use-after-free on error handling during VR view drawing

Whenever an exception happens in VR session code, we cancel the entire
session. Alongside that, we removed the "surface" item used to draw into
an offscreen context. But this may still be stored as active surface,
leading to a use-after-free when deactivating this active surface, for
example.
