Added .psd, .pbm/.pgm/.ppm, .pfm, and .hdr image formats. Extensions NOT added to r_imageextensions.
png (and the above formats) can now be loaded as RGBA16, instead of being truncated to RGBA8 (8bit pngs not affected).
r_imagelist will now show images from memory, instead of potentially loading new/different ones from disk.
Fix serverbrowser bug being too eager to join the server (eg from alt+tab).
Don't send ipv6 packets to qw/q2 masters. They won't be able to report ipv6 addresses anyway, and this reduces warnings when a host STILL has no ipv6 (my ISP sucks). this does not affect q3/dpmasters, for people without ipv4 addresses.
Tried to improve compat with Bloodshot's particle effects.
Fixed a couple of issues with R_AddTrisoup.
Fixed string tokenizing bug where it was using the wrong buffer size values.
Don't show link-local/localhost addresses in eg the status command (unless developer).
qtv-rel is now an easier target, for new qtv releases.
qtv warning fixes.
added a nailtrail effect to 'high' particles.
fixed terrain shaders.
fixed fogged water issue (on one of bal's maps).
first attempt at gltf2 format support
