Well, there are not much changes in flake. I just added new classes there.
And new tools can be written with them. Old ones can work as usual. All the
"invasive" changes will happen in KisTool and lower. Take into account that
these classes will be rewritten anyway while encapsulating their actions for
the scheduler. So these shortcut changes will be a kind of side-work =)

Yep, that is already done in flake. But noone uses it. We have 8
interactional tools only (5 in flake itself, 1 in each of karbon, tables,

The state machine of the switching is a good point actually. I need to think
it over. It should be generalized as well.

For most of the tools we can assume that we can do panning and rotation when
the user does not hold any mouse button pressed. This is the idea of
For all the interactional tools there is no such problem, because you can
know what it is doing by checking currentStrategy() pointer. And that is the
idea of KoInteractionToolStrategyWrapper.

How are you going to communicate between this global manager and all the
tools? And how will it process semi-global shortcuts, like the ones those
should be activated for KisToolPaint only? There should be more than two
layers of shortcuts.
