tweak some dp compatibility things. probably futile. moved ode to a plugin. added screenshot_mega command to take massive screenshots that are not tied to current video mode. removed offscreen-gecko code completely. added cvars to rescale offsetmapping from paletted sources, so it can be disabled where its ugly. added support for zip weak encryption. the password defaults to 'thisispublic'. nothing is fool-proof. gl: fix stereoscopic rendering. gl: fix rendertargets with depth. qc: added support for named builtins that do not have any specific number. qc: added some new builtins. drawrotpic, drawtextfield, search_getfilemtime, and a few others. qc: PF_Fixme now attempts to figure out which builtin you tried to call, for more friendly fatal error messages. qccgui: stepover and stepout are now implemented, as is setnextstatement. qccgui: added a way to annotate code with the asm statements generated from them. qccgui: fixed double-clicking a src file. qccgui: handles multiple .src files more usefully. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4832 fc73d0e0-1445-4013-8a0c-d673dee63da5
