Fix crash when iuser isn't available.

Moved UVWrapping to template argument of the sampler.

This adds back wrap repeat linear sampling.

Added support for 1, 2 and 3 channel float buffers.

Added support for 3 channel source buffers.

ImBuf transform: Added Sampler.

The sampler will hide the interpolation functions and would allow us

Sculpt-dev: More improvements to detail enhance

* Detail enhance is now it's own dedicated toolslot.
This makes it possible to use autosmooth with
detail enhance.

Note the behavior of the smooth brush (which
invokes enhance when pressing control)
is unchanged.

* Fixed a bug with temporary attribute layers being constantly
cleared and reallocated with multires.

* Cleaned up velocity smooth code a bit.
* Pruned various dead #if blocks.
* generate_from_enum_ex in space_toolsystem.py
now takes a special argument to combine enum
items. This is used to make enhance a subtool
of smooth.

Removed close curve functionality.

Sculpt-dev: another gcc fix

Sculpt-dev: more linux errors

Need to figure out -Wshadow equivalent
for msvc.
