hacky rendertarget stuff. not polished. don't use except for testing. feedback desired. switched file system to use a qofs_t type instead. define FS_64BIT to make it 64bit (standard on 64bit cpus). rewrote zip support, ditching unzip.c. this provided zip64 support, and unicode in zips. changed local address enumeration to not be so stupid. updated ode support a little to match some dp features. changed fs_cache scheme, to not rebuild needlessly. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4596 fc73d0e0-1445-4013-8a0c-d673dee63da5

//the pepper api is flawed. deeply flawed.

//1: api calls (including various gl calls) may only be made on the main thread).
|
|
//2: the main thread may not use non-asyncronous calls.
|
|
//the recommendation to get around this is to run everything on a worker thread, but to make calls to the main thread to do the actual call, then signal the worker thread to wake up again in the main thread's callback.
|
|
//which is impractical when you have 80+ different sorts of performance-dependant gl calls.
|
|
//I can't easily put things requiring file access on another thread, if only because it would make alias/exec console commands non-synchronous
|
|
//to get around this, I instead make my own memory-only 'filesystem', populating it at startup with downloads. I *really* hope your browser/server are set to enable file caching.
|
|
//at some point I'll periodically write the data back to a persistant store/reload it at startup so saved games/configs can work
