Tk's bad at pixel-oriented graphics; its [canvas]
is designed for higher-order manipulations (and
can be breathtakingly effective for many inter-
esting tasks).  People coming from other paradigms
can usually find ways to misuse Tk into sluggish-
ness.  The Unicode stuff in 8.1 is still being
shaken down; severe performance issues have turned
up there, but plenty of fixes are available and
are gradually being worked into the core.

If you're doing things that fit well in [canvas]es
and [text]s, you'll go far with Tk.  Several
widgets that moderns expect are *not* available
in the standard core, and some of the extensions
that provide them are not high in performance.
