preview-latex icon proposal

preview-latex now supports different icon sizes depending on the size
of the base font used in Emacs.  David already mentioned that the
quality of the smaller icons suffered a bit from scaling.  So here is
a proposal for a set of new icons which should scale better.  The
original was done in SVG format and the icons were exported directly,
so no scaling of bitmaps happened.

Here is a comparison of current and proposed icons:


The rounded edges of the new icons make the look a bit smoother and
provide more place for the content of the traffic signs which helps a
bit to preserve clarity even in smaller sizes.  David already
expressed his dislike for this roundedness.  So if you would like to
see those icons in the next preview-latex release, please speak up.
Of course also if you don't like them but that's not really
necessary. (c;  And please keep in mind that the quality of the icons
with the straight triangles could probably be enhanced once somebody
tries to model them in a vector-based program.

I am copying this message to both the AUCTeX and preview-latex mailing
lists as preview-latex will get integrated into AUCTeX sooner or later
and in order to reach a bit more people.
