MAINT-1894: FIX This *should* fix a crash in the LLVolume::resizePath() method. The callstacks indicated that the std library was throwing a length exception on the std::vector::resize() call. Most likely cause was that the recent changes for flexi-prims were causing the mRenderRes to become negative. And thus, the 1<<mRenderRes calculation was generating a really large value for num_render_sections.
