Uses the bglFlush() and is_a_really_crappy_intel_card() hacks to give

better support on low-end Macintoshes with integrated Intel graphics
chipsets.  Patch received from "UncleZiev" on #blendercoders, but I
adjusted it so other video chipsets and platforms are unaffected.

The only visual difference is that on MacBook and iMac machines, the box
select outline is drawn with solid, not dashed lines like other platforms
and not invisible as they were previously.
