Slow rotation after presets used

[goddard@…]

The following bug report has been submitted:
Platform:        Darwin-17.7.0-x86_64-i386-64bit
ChimeraX Version: 0.7 (2018-08-02)
Description
Rotating 5cd4 is very slow (a few frames per second) after using Preset / Cartoon followed by Preset / Original Look.  The number of triangles per sphere ends up at 2000 but should be much smaller.  This did not happen with 6caj which does not have nucleotides.  Greg says nucleotides does some explicit level of detail call that is perhaps related to the failure of level of detail to adjust properly.

Fixed.

Level of detail updating sometimes did not happen depending on order that "graphics update" triggers fired in.
