A few changes. Half-Life support is finally getting committed. Some unnecessary filesystem code changes. And there's code for nsapi - meaning we can embed FTE in a browser (firefox and opera on windows work). A couple of CSQC changes, trying to move towards a final EXT_CSQC_1. Revised ruleset format finally implemented. Doesn't compile with msvc6 due to issues with libjpeg not being a clean library. Presumably its fine in vs2005. Your mileage may vary. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@3148 fc73d0e0-1445-4013-8a0c-d673dee63da5
