Update CHANGELOG and API_CHANGES for Manuel Metz's errorbar patch.

Errorbar limit symbols patch by Manuel Metz

Fix some obvious bugs in Type 1 font support; now it at least
produces a pdf file, at least with Computer Modern Roman, but
viewer applications complain that the fonts are broken.

Created new file type1font.py for supporting Type 1 fonts;
quite preliminary for now. Started adding Type 1 support to
PDF backend for purposes of usetex.

Added example of a standalone colorbar.

Fix buglet in get_text_width_height_descent of backend_agg
when text.usetex is in effect. The descent returned is probably
not correct, but it should be similar to the one returned by
backend_ps.

Some refactoring of dviread, plus a reader for psfonts.map format files

Fix log expression.

Render all the fonts in each mathtext expression to a single image buffer
(memory and time savings).
Add support for getting raw image data for mathtext expressions.
Add mathtext_wx.py example showing how to put mathtext expressions
into controls.
