Subject Re: [FlexJS] backgroundAlpha doesn't work

will probably want to use an RGBA.

Forgot to add that backgroundAlpha on the AS side effects both background colour and background
image so it seems reasonable to keep it the same on the JS side (as above)

If you remove background alpha and only use RGBA colours then there no way to set background
alpha on images in AS/JS. So perhaps removing it isn’t a good idea?
