Sample code (https://github.com/kcvinker/Winforms) is broken

Doesn't compile - multiple issues, whereas this one compiles fine: https://github.com/kcvinker/Winforms/blob/master/app.odin

I am working on a change to the button-drawing code. Once that is finished, I will fix this issue as well. Thank you!
