get rid of to_text

I've been misunderstanding what Text objects are. They can render a lot
of text with a given line height, word wrap, colors in various places.
And I've been creating one for every word :facepalm:

Unwinding this will take some time. This is just a first baby step for
ad hoc text objects. Turns out I don't need to convert to Text to get
something's rendered width, just the Font can do that.

Thanks to the LÖVE Discord for educating me:
