Subject: Fixed Issue 191: Add new opengl.1thread=new or similar
A new recognized option -Dopengl.1thread=worker has been added to the
Threading class and is now the default. Optimization has been added to
leave the last context current on that thread so in the single-context
case context switching is avoided. Code has been added to make this
interoperate well with the manual use of the GLContext APIs.
