>Description:

By default, the eps2png program uses the resolution of 82, which is too
low. 10 point text in Courier is rendered completely illegible. That
creates the temptation to produce larger EPS originals. However, that
would make them too large for PS and PDF output (10 point Courier is
the standard default font/size for the typical printer).
>How-To-Repeat:
	
>Fix:
Introduce a PNG_RES in doc.images.mk, set it to 100 (unless it has already
been set to a different value by the user or the Makefile).

Add -res ${PNG_RES} to the eps2png command line.
