This is in VW7.6:
I was looking to bitblt using:
Image>>copy:from:in:rule:
but could not find the meaning of the rule: argument. I eventually
found the documentation by looking for senders. For example:
BrowserTabApplication>>eraseBackgroundOnImage: anImage
has an in-method comment describing the bitblt rules. Several other
methods have the same comment. Would make more sense in the Image
class, no?
