Sculpt: Fix possible race condition with undo nodes

it is possible that two threads will request same undo node, only one
of them will initialize the node. The issue is that initialization is
happening outside of a lock, which was making one thread to use non-
initialized node.

If this change is ever a bottleneck, make a lock inside of node.

Workbench: Fix texture drawing

Workbench: Fix ghosting and crash in X-Ray mode

When playing animations the anti-aliasing was not reset, resulting in
ghosts from previous frames to be drawn. Also when playing animations
and switching to X-Ray mode for the first time would most likely
result in a write to uninitialized memory.

Cleanup: typos
