source: trunk/src/ddraw/asmutil.asm@ 2511

Last change on this file since 2511 was 2174, checked in by hugh, 26 years ago

Added ODIn lic header with ID to all files where missing

Cleaned up Surface handling by movefing colorfill and
colorconversion into own files and use functionpointers
setup during creation.

updated makefile to add files

removed inhertiance from IBASE in DDrectangle class
