Remove euclid dependency

[kvark]

It's unclear what value euclud brings here. A cursory look reveals only Point2D and Size2D used, and surfman could just roll out its own structures for this.

@kvark I'd like to take a look at this, but I'm a little confused as to how to approach the problem. Should I make my own definitions of the Euclid structures, and if so, where in the codebase should I store them and refer all other calls to those structures to? Thanks!

[kvark]

@avr1 Sorry! I stopped using surfman in gfx-rs and opted into talking to EGL directly instead, so I can't help here.

[avr1]

Thanks anyway! @jdm, do you think I should make my own definitions of the Euclid structures used, and if so, where do you suggest I put them? If not, should we continue to use euclid?

[jdm]

Yeah, I would just put them in the root of surfman, or maybe make a geom module that's publicly visible.

[avr1]

@jdm Sorry to ask such a newb question, but where exactly is the root of surfman, and how would I access that in the subdirectories? I've been fighting a losing war with the module system.

From submodules you could refer to use crate::{Size2D, Point2D};
