Updated Predefined Brush engine

[Dmitry Kazakov]

Hi, all!

As you might have already seen, I've just pushed quite a big patch for the
predefined brush engine. It might be really cool if someone tested whether
it introduces any regressions into the painting.

The patch fixes 4 bugs and should make the painting with the predefined
brushes about 10-20% faster. The list of the fixed bugs is the following:
1) https://bugs.kde.org/show_bug.cgi?id=320651 (part 2)
2) https://bugs.kde.org/show_bug.cgi?id=320368
3) https://bugs.kde.org/show_bug.cgi?id=319944
4) https://bugs.kde.org/show_bug.cgi?id=300665 (yeah, the sparks brush is
finally fixed!)

What needs to be tested:

1) Painting with Predefined, Custom and Clipboard brushes
2) Painting with both: "Use Color as Alpha" on and off.
3) Painting with very small scale (1px brushes) with subpixel precision
(this point is very important for I don't know how to test it ;) )

All the comments and suggestions are welcome! :)
