I'm using gpr_$text to draw characters on the screen. 
Suppose I have the text background color set to white, and
the text drawing color set to black, and imagine drawing text
onto a solid black screen.  Rather than getting a contiguous
white box with the characters in it, I get a bunch of
discontiguous white boxes with black gaps between them --
which is not what I want.

Question:  is this a bug or a "feature"?  I expect I could
fix it by hacking the bounding boxes of the characters, but
the standard system fonts all behave this way.  Is there
something else I can do (adjusting the character width, or
something?)  Otherwise I am forced to clear the entire text
box before drawing in it, which is time-consuming and
visually unpleasing.
