Q3Map2/VIS

VIS phase minor switches

-fast

Only calculates rough visibility data. Quick and dirty, not actually useful for VIS purposes.

-hint

Will merge the bsp leaves (except for hint portals) before calculating the visibility list.

-merge

Will merge the bsp leaves before calculating the visibility list.

-nopassage

Disables the passage visibility algorithm. Passage VIS is a bit faster and tighter than the old algorithm.

-nosort

Disables the sorting of portals by complexity. Sorting speeds up visibility calculations.

-passageOnly

Will use the passage visibility algorithm only.

-saveprt

Disables the automatic deletion of the .prt portal file after VIS finishes.

-v

Enables verbose mode. Always use this.
