and another two changes:

1. [alpha]

now you can set the blending-function 0..GL_ONE_MINUS_SRC_ALPHA that's the (old) default 1..GL_ONE (as would be enabled by the "blend" message to various objects.

2. [polygon_smooth]

enables polygon smoothing

i think this is better than having to add the "blend" method to all Geos. So users can decide what they need. (and they need to know about it anyhow)

i think [polygon_smooth] is a bad name. but which one would be better ?

i'll try this out later today. the main reason i added the blending stuff to the geos was to get anti-aliasing. those jagged objects were pretty ugly to look at!! the side benefit is of course having alpha blending 'for free' on the gpu.

i have no suggestions for [polygon-smooth] right now, but then again i'm always having trouble naming these objects. at least it describes what the object does.
