Multiline examples

[JiffyRob]

This contains a commit for every example listed and not covered in issue #2206 except for playmus. The default wrapping behaviour may not be desired for dropevent though:

I tried not to change too much but the joystick example got the TextPrint class removed and the music fade example's constants and globals were put to the top (because I just could not wrap my head around the code else). The font viewer is also left aligned now because multiline rendering does not center text. I'm open to change this if necessary.

This looks good to me, thanks for working through this.

I'd like someone with joystick hardware to review the joystick example, if possible. I can't really test it in action because I don't have any joysticsks.

I did test it with a USB gamepad and AFAIK it did everything properly. That said, I can't give a screenshot and a maintainer ought to test it anyway

This looks good to me, but like Starbuck5, I can't test it myself. I'm not merging it because someone else should test it first

Tested the joystick example, and left some notes.

Also, you can set font.align to be centered for the dropevent example, I think that way it does look better.

It seems like the joystick example notes have been resolved, so I'm going to go ahead and merge. Thanks for working on this JiffyRob!
