| | | | | | code automatically call the proper functions depending if compilation is for greylib or color display, also forms proper call to grey_ and xlcd_. mylcd_ub_ call greylib unbuffered routines, regular lcd routines otherwise. Form is mylcd_<fnname>, <fnname> is the symbol name stripped of prefixes lcd_, grey_, or xlcd_. Convert a couple plugins I know well (easy job). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26542 a1c6a512-1295-4272-9138-f99709370657
