updated documentation - added handler / callback prototype section, added key names section; added ag::drawArc() and ag::drawCircle() w/ documentation; added tests/transparent.png and tests/imagetest.lua; renamed init() event to init_event(); re-added missing drawImage Lua hook; changed images to draw transparent parts correctly through to background
