ofSetCircleResolution: fix so ofRectRounded gets affected by ofSetCircleResolution
No value has been assigned to 'speed' causing it to be assigned 0.0f. This causes some chipmunk effects when using the SoundPool on certain devices.

The speed is the playback rate of the SoundPool object. It ranges from 0.5 to 2.0. The normal playback rate is 1.0.
This will get rid of the "mediaplayer went away with unhandled events" messages when unloading the MediaPlayer objects.
