From a short view this looks like a mix of convenience methods (ie something
like converting between world and display coordinates using a transformation
matrix), ad some Krita specifics (I don't think other applications need
exactly one input device, or they just support a fixed device like the
mouse)
An interesting thing are the updateCanvas methods. IMHO this is really the
base functionality of a canvas (updating dirty regions).
The question is if this has to be a virtual method, or if there could exist
a base implementation.
