   when you say "the pixel at 30,y will be rendered", do you
   mean between 30 and 31, or do you mean between 29 and 30?

I don't mean "between" anything.  My mental model of the
mapping of a coordinate component to a screen pixel (in X) is
direct.  It doesn't admit subpixel (fractional) specification.
Left-most pixel is numbered 0, and "at 0" refers to that pixel.

So in my description "at" is actually superfluous.  Thanks for
prompting this realization!  Please (re-)read as "pixel 30,y".

   More importantly, if you remove the "- 1" part, per my
   suggested patch, do you see a change in the cursor
   dimensions when you toggle a window between selected
   (filled block cursor) and non-selected (hollow block
   cursor) status?

I confess i haven't yet run the test case, but just jumped
into the discussion pedantically.

   This sentence didn't parse.  How the rectangle is specified
   is described on the same page, so you've probably read that
   already.

Likewise, i have not visited that page.  All i know is that
there are different models for describing a rectangle (even
w/in the same system -- e.g., SDL "rectangle" and SDL_gfx
"draw rectangle") and that surfing among them one finds many
OBOEs sounding right and left...  :-D
