source: abuse/trunk/src/lisp/trig.cpp @ 524

Last change on this file since 524 was 524, checked in by Sam Hocevar, 11 years ago

core: Get rid of mostly useless headers, move endianness handling to
common.h (and rewrite functions so that they do not need the SDL headers)
and move a few functions out of sdlport's video.cpp. These functions
were in the original video.cpp (which reappears) and shouldn't be part
of the SDL port.
