Newbie questions ...

I'm thinking about buying tgb but i had a couple of questions that i wanted to ask first and this seems the best place. does tgb support the usage of svg's and if so, how hard is it to implement some zoom in/out effects? it's pretty easy in flash, but slow as a dog especially when you got alot to zoom. also i suppose it supports joysticks/pads ... how many total? i had an idea for a series of 4-player party-style games (think mario party) that i would like to possibly do with tgb. i think that's it for now, and i appreciate the feedback.
