You're right -- I stand corrected.

OK.  That, having been said, makes me wonder, "What is a good cut-off size
for GTK, before considering using external modules?"

If you do include stuff into GTK, there should be some research on how
useful the widget will be.  GTK currently has rulers, which are godsend
for document-based programs.  GTK has support for buttons, lists, trees,
etc.  That I can also live with, as they have a high frequency of use in
common software.  Font selector was long overdue.  :-)  But all possible
widgets?

I'd hate to be the person on the other end of a 33.6kbps connection
downloading GTK+-5.0, with its 10MB binary.  Imagine the size of the
source code?  8-D  OUCH!

You are sick and evil if you make a program that's 500MB in size... :D

Bloat-ware.

Perhaps.  Is it possible to use external shared libs with GTK now (instead
of static linking)?  I'd imagine so, since shared libraries often look
like static libraries to all parties involved.
