_imagingTk is not needed for Skencil.  It doesn't hurt to compile PIL
with it but Skencil doesn't use it.

There are two optional depencies: If you want to use the SVG import
filter you need the PyXML package and for PDF export you need reportlab.
Links are on the web-page.

It doesn't matter.  The name is only the basename of the file anyway.
The alias file is there so that more than one basename can be associated
with a font name.  When Skencil searches for a file it tries all the
basenames with the appropriate extension appended, regardless of whether
it looks for an afm file or a pfb.

In that situation you don't need an alias file.  I only added the alias
file because some common fonts are often available with different
basenames.  E.g. the metrics distributed with Skencil use the names used
in TeX but the actual font files used are often the ones from
Ghostscript which use different names.

The font name identifies the font in Skencil.  It's stored in the .sk
files, for istance, and it's used in the PostScript code generated by
Skencil, because it's also the name under which it's known to
PostScript.
