[Bf-blender-cvs] [1ea5c2a] master: Fix remaining sculpt mode crash using multires modifier, similar cause to previous sculpt fix (OpenGL access from thread with no context bound). The fact that this has gone unnoticed so far means that people are dyntopoing like crazy these days.

Fix remaining sculpt mode crash using multires modifier, similar cause
to previous sculpt fix (OpenGL access from thread with no context
