Renamed graphics functions

[ceeac]

As part of the graphics backend refactor (r11927) a number of function names in simgraph.h were changed; the old and new names can be found in the table below.
Functions marked with (*) are very likely going to be moved from simgraph to font_t to reduce code duplication in simgraph16 and a future simgraphgl, and to prepare support for multiple display fonts.

[prissi]

These names are much more sensible, given that the old fixed font is gone as is some other things which led to those names.
