Re: [RP] aspect ratios...

[Greg Minshall]

hi.  more on this.  poking around, i see i was wrong (and Jérémie was
right) about gnuplot *not* using aspect ratio hints.  so, i played
around with that.  the below summarizes my changes; {PARAM} was a value
i played with.

with {PARAM} set to 1 (so, max_{width,height} are just the size of the
plot), i get the window aspect ratio i want.  but, it takes up only a
small part of the geometry available to it.  so, i set {PARAM} to 100
(to look "greedy").  with this setting, i get a window that takes up all
the space available to it (good), but then the aspect ratio (whose hints
i've provided) is ignored (bad).

below also is (the relevant part of) what "xwininfo -stats -size" says
in that latter case.  reading it, it seems to me the aspect ratio hints
are set (correctly?), but the geometry of the window is *not* a multiple
of this aspect ratio.  i *see* (but haven't played around with) the code
in ratpoison/src/manage.c that seems to be trying to honor my hints.

any ideas what i might be doing wrong?

cheers, Greg
