# PDF files created with usetex now embed subsets of Type 1 fonts

When using the PDF backend with the usetex feature, Matplotlib calls TeX
to render the text and formulas in the figure. The fonts that get used
are usually \"Type 1\" fonts. They used to be embedded in full but are
now limited to the glyphs that are actually used in the figure. This
reduces the size of the resulting PDF files.
