This appears to fix an issue where the screen would occasionally flicker
after resuming from dpms' screen blanking feature. So far I have not
observed any significant performance degradations.

This likely fixes an issue I had earlier, although I don't remember what
it was. In any case, this change is a positive one since toggling the
bar is now instantaneous as well.
Since the device we're using is normal DPI, we have to manually adjust
these two values. Note that the rest of the setup is mostly automated
when it comes to determining the size of things.
