1f4f50682c Make VOID and BHOL eat stickmen again 
Broken by making stickmen heads pass through everything, since the eating
happened in try_move, which stickmen no longer use for head movement.

966f1dcc23 Use atan2 for LIGH angle calculations 
atan2 gives the actual angle (in the range -pi to pi). acos and asin just
give the principal value (in the range 0 to pi, or -pi/2 to pi/2)

ded23cfa94 Fix minor bug with deco sample tool 
If particles are not being drawn with blendpixel, then it is possible for the
R/G/B component of a pixel to be 255. Adding 1 gives 256, which does not
produce the right colour when combined into a RRGGBB value

a104696620 Update to EXOT that makes it permeable to neutrons as well as electrons. Neutrons cause a water>distilled water spread that enables EXOT's copy function, at its original speed. Electrons reset mode, but not tmp2. Trippy monochrome colors for copy mode.

6c3034acff Make ambient heat convection work a bit better 
Previously, it was comparing the temperature of the current cell to the
average of the cells around it (plus some advection affecting the
average, but that makes no difference if the air starts out stationary),
and basing the velocity change on this temperature difference.

If the cell below is hotter and the cell above is cooler, the air should
rise. But in this case, the average of surrounding cells tends to be
near the temperature of the current cell, so not much happens.

Just using the temperature difference between the current cell and the
cell above makes convection work a lot better.

6d307b47b5 Revert "Make THDR TYPE_ENERGY again, so it goes in photon map" 
This reverts commit 8b20bfd764.

TYPE_ENERGY makes THDR move like photons, and means adjacent particles
don't conduct as much heat from it (since the heat conduction code only
looks for particles in pmap, not photons).

Heat transfer could be fixed by increasing THDR's heat conductivity, but
gas or powder movement is probably better than photon movement for THDR.

303a32f290 Avoid stacking in INVS and FILT, and fix pressurised INVS graphics 
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.
