Color isn't printed when using a graphical tablet

[vpatkov]

When I'm using a graphical tablet (Wacom CTL-471) color isn't printed on click. With mouse it works ok.

I suppose this is because tablet's pen is almost impossible to keep still and so it continuously updates the cursor position. When I move up the pen so it no longer is seen by the tablet and the cursor stops, and then execute xdottool click 1, xcolor is succesfully prints the color.

Probably it's the same issue as #32.
