Subject: [E-devel] [PATCH] Patch for elm_slider.c (if you click the
bar of the slider, the button will be at there.)

I made one patch for elm_slider.c file.

If you click the bar of the slider, the button will be located at there.

(If you keep your "mouse_down" after moving of the button, you can
continuously move the button.)
