[PD] Pd internal font size inconsistency on Raspbian

Hi katja,
Could you do a test?  Make a simple patch with a single object in it, and use the same canvas font size you did above.  Then run Pd with -d 3 flag and see what font size is actually being sent from Pd to the GUI on each distro.

A particular font size issue can be observed in vanilla Pd and package
puredata on Raspbian Wheezy and Jessie: font size 10 is larger for
object boxes, message boxes and comments than for IEM guis (bang,
toggle, slider, radio button, canvas). Object/message/comment
characters are too large in number of pixels. When Edit > Font > Font
Size is set to 8, their size is identical to IEM gui font size 10.
This inconsistency does not happen for me on Xubuntu. A test patch and
two screenshots are attached for illustration.

For IEM guis, font size 10 translates to 6 pixels per character on
both systems, given the default font type DejaVu Sans Mono. For object
boxes, message boxes and comments, font size 10 is 6 pixels on Xubuntu
and almost 7 pixels on Raspbian.

I don't know if this issue is related to font size effects on Windows
as described by Roman in another thread. In any case, consequences are
similar: patches created on Xubuntu tend to look messy on Raspbian,
sometimes with overlapping texts. With XFCE (Xubuntu's default desktop
environment) installed on Raspbian the issue still persists. Custom
dpi setting has no effect on Pd. What else might cause the difference
in behavior on those systems?
