Cleanup: const args for curve handle calculation

Cleanup: use defines for handles

Copied from original function.

Correct comments

CMake: check for minimum MSVC version

Needed since older versions are unsupported (giving cryptic errors).

Remove paste-from-file from menu

Operator no longer exists.

UI: Use zoom in/out icons for curves

Was confusing since zoom icons were used for add/remove elsewhere (color-ramp & presets).

Link windows builds against Blosc when OpenVDB is enabled

OpenVDB is compiled with Blosc support, meaning we should pass Blosc to
a linker now.

Unfortunately, the Blosc has compiled-in crt and pthread library, which
still screws up linking.

Fix race condition in point density texture min/max code

Cycles: Fix bug in CMJ pattern when number of samples is 1

It was wrongly considering 1 is a power of 2. While it is a correct thing
(1 == 2^0) it's not what the math in some later formulas expects.

UI: expose soft limits to custom-property editor

Internally custom-id-properties used soft-limits, but there was no way to edit these.

Fix (unreported) crash when opening a file from splash screen when 'load UI' option is disabled.

Took me some time to figure out what was going on here... Was again that delayed button
callback stuff (`ui_apply_but_funcs_after()`), first calling button op, and then
its callback func.

Issue was that 'open file' op (through call to `WM_file_read()`) would clear
the splash screen (as more or less the entire 'dynamic' UI), but callback func of that splash
(`wm_block_splash_refreshmenu()`) would still try to access that freed menu's region.

So, root of the issue seems to be that setting context's wm/win/etc. would not clear
context's menu pointer (while clearing all other 'sub' pointers). I could not find
nor imagine any case where this behavior could be desired, so simply added nullification
of that pointer when setting context's wm/win/etc.

Note that crash was due to read-after-free, infuriating debug builds with asan,
but seems like release builds never actually crashed on it.

Fix T47444: Texture node in compositing nodes does not update

bplayer compile fix (c)

Point density: Removed wrong line in previous commit

Thanks Bastien for finding this out!

Remove unused "Free Unused" option from compositor

It was basically doing nothing, for ages.

Make point density sampling threaded

It should be all fine to sample same point density from multiple threads,
this is something what Blender Internal is doing actually.

Fix memory leak in point density

The issue was happening when having unconnected point density which
will cache data but will not free it because there's no actual call
to the actual sampling.

Now the idea is to make sure cache is zeroed on file load and undo
and then caching via RNA will free the data if any exists. This could
leave us with a single copy of cache in the node if it's not used,
but it's quite small amount of memory and it's not leaking.
