touchmove draws when touch point is outside the grid #23

Hi,

I introduced a defect in #20 related to touchmove. If you start touching in the grid and moving to the right out of grid boundaries, some cells of the grid are painted. This is because horitzontal coordinate should be lower than columns and this validition is not performed.

Cheers!
