`flip` transformation #6

Open miniBill opened 4 years ago

miniBill commented 4 years ago

I think the package could use a flipHorizontally/flipVertically pair of functions.

My use case is flipping an image (otherwise I'd need two versions of the same image, one normal and one flipped).

i would suggest instead of flip - add scaleX and scaleY - that can solve that problem, and add more functionality, and flipHorizontally - would be just alias to scaleX -1
