Fix T78028: crash with grease pencil and save buffers

Perform grease pencil rendering delayed in this case, as there are no render
buffers available for compositing. This keeps memory usage lower, but does
involve multiple depsgraph evaluation. This seems in line with the intent of
the save buffers feature, to use minimal memory.

Fix potential crash closing Blender with persistent data option enabled

Found by address sanitizer.

Fix T78956: banding artifacts of vertex colors in Cycles

Byte colors must be encoded in sRGB and converted to linear on lookup,
to avoid precision loss.

Cleanup: more renaming in the render/ module for consistency

Pointclouds: move blenkernel code to c++

Fluid: Fix strict compiler warning

Proper way to check for DEBUG_PRINT is to do `if defined` check rather
than `if`: this is because in non-debug builds the symbol is not defined.

Cleanup: fix wrong merge, remove extra unique_ptr.

Fix T80068: skin modifier not working with motion blur

The skin modifier did not output consistent results, causing failure to find
corresponding vertices across frames.

Remove unnecessary use of GSet, all we need is an array.

Cycles: fix Node::tag_modified not setting modified flag's upper bits

Previous code was flipping the bits on a 32-bit number and doing a zero extension to cast to 64-bit, so mark the constant as long to begin with.

This would also erase previously set bits in this part the flag.

Cycles: Fix function inline attributes

forceinline attribute is only applicable for function which are
marked inline. Interestingly, it can be used for class methods
without explicit inline statement. But for functions it is another
story.

macOS: follow system preference for natural trackpad scroll direction

And remove Blender preference, which was expected to be set to match the system
preference for correct behavior. Instead just handle this automatically.
