Revision:
98:ecebed9b80b2
Parent:
95:ef538bd687c0
Child:
100:0b084475d5a9
Significant changes to the support for Soft Fonts (User defined fonts), to directly leverage the output of the GLCD Font Creator tool and require nearly zero manual changes. This deprecates the old API setfont in favor of SelectUserFont.
