Texer II alpha

[UnConeD]

After an afternoon of trying to iron out the final showstoppers, texer 2 is finally working . Changes with texer 1:

- Support for all blend modes (use Misc / Set Render Mode)
- Support for resizable particles
- Includes a standard bitmap (thanks Tuggummi)

And finally, it's now directly codable so this means:
- Subpixel accuracy when resizing is on
- Overlapping particles are possible
- No more disappearing particles at the edges

Get it from:
http://acko.net/t2/texer2.zip

Includes two 3D presets showing off how to use the resize ability for 3D particle rendering. Basically you set sizex and sizey to 1/z.

The help is still to-do (I mailed justin to ask if it's possible to include the standard help panel like in a superscope/dm), but you shouldn't have much trouble with it because it behaves mostly like a superscope.

It seems stable here, but crashes are always possible. However because it uses the AVS scripting library, it's possible that one of the AVS bugs can trigger when working with Texer2, and there's not much I can do about that.

Oh by the way, I need a couple of simple examples for inclusion. If anyone feels up to it .

This version is not final, but the code interface won't change anymore. Only bugfixes/additions.
