Feature request: DrawTarget::write_png_to_memory

[Maldela]

Hi!
I think a function for DrawTarget to write a png encoded image to a Vec would be useful.
Right now it only writes a png file to a given Path which is not helpful, if you want to use the data in your program.

This seems reasonable. I might make it so it just takes a w: Write.

Perfect

Nevermind. I was just too stupid to use the raw data.
