Added option to define select threshold

Clamped t between 0.1 and 0.9

Merge master

Clamped t to not let curves go to infinity

Add ID_remapper.

Currently not being used.

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.

Cleanup: Use pixel in stead of texels in naming.

Fix compile errors on windows.

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.

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.

Cleanup: unused variable warning

Cleanup: remove disabled code

Originally pointcache wasn't supported when the file wasn't saved.
Remove commented code as this hasn't been the case for a long time.

Cleanup: resolve parameter mis-matches in doc-strings

Renamed or removed parameters which no longer exist.
