Birthing particles using a map

[hughwyeth]

The Position Object operator has a texture parameter which allows you to position particles on an object based on texture luminosity. So the order of operators would be:

1) Birth operator, specifying how many particles you want
2) Position Object operator, using your cloth as the input object, with a texmap assignment which determines where particles will be birthed, based on texmap intensity.

Make sure you're using a texmap with explicit map coordinates. For example, a Noise map in world/object mode won't work, but in explicit map mode it will.

That's awesome, thanks so much!
