fteqw/engine/qclib/pr_multi.c
Spoike c4d3497054 some Q2 compat tweaks. moved all q2 temp-ents to particle scripts. 
PF_VarString can now shortcircuit, directly returning the first argument (which also bypasses related length limitations). this required const correctness fixes.
r_showshaders cvar reports the wall texture being pointed at.
improve dp compat in a number of areas, should now mostly be able to run xonotic 0.8.2, but will need some more extra cvars/defaults/stuff.
fix q3bsp loader race condition.
fix dpm loader multi-surface issue.
remove limit on stringbuffer count.
don't poll xinput (because its disturbingly slow), instead wait for some window message before re-checking.
fixed splitscreen saved games.
