but filters can't be put inside a colorstrategy.

in tile manager data are stored in uchar* (uchar is the smallest data 
division, except for boolean, which are stored in uchar...).

a double equal four uchar, imagine we have a colorstrategy with 3 double 
channels, and one uchar channel. The KisPixelRepresentation will look like 
this :

KisPixelRepresentationMyColorStrategy : public  KisPixelRepresentation 
{

KisChannelDouble channel1() { return  KisChannelDouble( (double*) data ); };
KisChannelDouble channel2() { return  KisChannelDouble( (double*) ( data + 
sizeof(double) ) ); };
KisChannelDouble channel3() { return  KisChannelDouble( (double*) ( data + 
2*sizeof(double) ) ); };
KisChannelUChar channel4() { return  KisChannelUChar ( data + 3 
*sizeof(double) ); };


private:
 uchar* data;

}

KisChannelSmthg look like  the current KisQuantum.
