Avoid stacking in INVS and FILT, and fix pressurised INVS graphics

Browse Source 
Collisions now always work for particles inside INVS and FILT, so
particles don't stack (just a single particle on top of each INVS/FILT).

Pressurised INVS was being drawn using PMODE_FLAT (with no alpha
blending), which sometimes hid particles inside INVS.

Also limit BHOL tmp value to make sure it saves correctly.
