it should be possilbe to turn off the call to glFinish
(apparently, some GLs work fine without) and to enable a
small delay in the buffer swap code (the nvidia drivers,
for example, use 100% cpu while waiting for a buffer
swap which is a huge waste of energy)
Those two things are one request because the
implementation will be in exactly the same functions and
the setting will be both in the tweaks submenu.

    glFlush can be added as a third alternative to glFinish.

    Done. The manual delay does not seem to be required since
    at least NVidia OpenGL stops using 100% CPU when you
    don't call glFinish. Don't ask ME how that is supposed to make
    sense...
