...well, if it is a bad shark trace, then it's highly reproducible ;-\
...As expected, OglProfiler reports that we spend only ~2% of app
time in GL, and of that, ~63% is in glBufferData(), which would be
expected...it does remind me that I need to switch [vertex_draw] to
not always using glBufferData(), but instead use glMapBuffer/
glUnMapBuffer or glBufferSubData() if the data hasn't changed size...
