FR: Some simple brush control protocols - flip ratio, reset ratio

raelly been getting into and enjoying just altering the brushes as I edit.

I find my self needing to go switch between a narrow horizontal brush, and pretty much an equal but vertical narrow brush. Being able to just flip them with a hotkey would be fantastic.

Also, resetting to perfect circle. I thought maybe just holding both increase/decrease ration buttons at the same time for a second would zero the brush ratio.
