[Android-development] Fwd: Nine-Patch Images

[Filip Piechocki]

But on the other hand - maybe it should be really a separate item
(NinePatchImage) - because rather no one would be changing the "ninePatch"
property in run-time (can't imagine such a case) so if someone is decided
to use the nine-patch image (like made with draw9patch) then rather doesn't
need border properties or sci functionality. But it would be nice to hear
the Qt guys opinion.

Best regards,
Filip Piechocki
