HunkMaster - HLDS memory filter

[Archive-Poster]

Ok, what is this? HLDS stores unnecessary data in memory - for example whole textures, sprites or lightmaps. So i hooked alloc functions and filtered it out. It frees about 10MBs of memory depending on map size. I also made public functions for listing memory. Now you can set correct -heapsize value depending on real usage.

Configuring
At default, HunkMaster filteres everything that is not vital. You can change it by cvar hm_discard. It takes bitmask as parameter:

filter textures: 1
filter bsp data: 2
filter common sprites: 4
filter unnecessary sprite frames: 8

It is 15 at default.
HunkMaster has it's own config file hm.cfg in game or mod dir. If it doesn't exists, it will be created.

Functions
Hunk_Print - Prints info about used memory into file mem.txt in mod dir.
Hunk_Print 1 - Prints more detailed info into... ditto.
Cache_Print - Prints info about used cache... ditto.
You can clear cache with command flush.

Disclaimer
This is highly experimental and it comes with no warranty at all.
...aaand it's windows only at the moment - but i could try to rewrite it for linux, if there would be a demand.

Appendix
It acts as amxx module, but it doesn't export anything for amxx, so it is more like metamod module.
