Description Martin Flöser 2012-07-10 15:51:42 UTC

Screen/WindowPaintData is showing two real issues:
1. it has public members which are read/written everywhere
2. it uses double for translation/scale/opacity/brightness

These two issues can be addressed by refactoring the classes to have a sane API and using qreal everywhere. This will make it easier to have the final conversion to float just in one place.

Git commit 8d6f6b3f3f73d67f955c1335a05a672d6cc994bf by Martin Gräßlin.
Committed on 12/07/2012 at 17:20.
Pushed by graesslin into branch 'master'.

Getter/setters for opacity, saturation and brightness in WindowPaintData

The public member variables for opacity, saturation and brightness
are removed in favor for getter and setters. The variables are
moved into a private class. Those are now qreal instead of double.

To make usage inside the effects easier a multiply method is added
which multiplies the current value with passed in factor and returns
the new value in a functional programming style.

This commit is the top-most of a patch series to refactor
ScreenPaintData and WindowPaintData. Other related commits are:
