net: revert the player angles inversion thing from last build. hack some angles. gonna need to tweak the protocol. net: cl_lerp_players is smoother, and defaulted. lets see how many people complain. cl: fix juddering with chase_active+prediction. cl: download progress where the total size is not known now displays something more sane. cl: fixed some issues with rawinput keyboards. cl: added autoupdate option to the menu. cl: autoupdate defaults to a new 'tested' set of builds, instead of the completely untested svn builds. cl: added 'borderless windowed' option to the menus. works on windows. cl: saved games save a preview screenshot. cl: fix some memory leaks on shutdown. cl: added 'setrenderer random' option, might be useful for modders in that it helps highlight bugs/differences between renderers... qc: r_showbboxes now displays the fields of the various entities. tweaked entity lighting to overbright more gracefully. gl: fixed crepuscular lighting. qcc: added % operator. qcc: added inline keyword. qcc: some fixes for accessors. qccgui: now prompts for exe+basedir. sv: added sv_specprint, ala mvdsv. sv: stats now sent over the unreliable channel instead of the reliable one. this allows them to change more frequently. sv: rewrote speedcheat detection. clients will be throttled instead of kicked. unresponsive clients will be simulated instead of freezing in mid-air. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4829 fc73d0e0-1445-4013-8a0c-d673dee63da5

//this is a post-processing shader, drawn in 2d
|
|
//there will be a render target containing sky surfaces drawn with crepuscular_sky, and everything else drawn with crepuscular_opaque (to mask out the sky)
|
|
//this shader then just smudges the sky out a bit as though its coming from the sun or whatever through the clouds.
