[PD] Pd internal font size inconsistency on Raspbian

[Jonathan Wilkes]

For the official record-- I'm holding my tongue, in the hopes that when others look at the codein my GUI port they'll practice similar restraint.

Ok, add this:
pdtk_post "for real this time-- the actual font we are sending to tk is: [set [get_font_for_size $font_size]]\n"

The answer is in both cases:

"the actual font we are sending to tk is: ::pd_font_10"
