We do not constrain the slider size anymore since it was ignoring the padding. Also paint the slider thumb on the step it was suppose to be painted. WebKit will now take care of the positioning of the
thumb, the behavior will be now more coherent with other ports.
As side effect, this patch also fixes setting a slider RTL that wasn't working before and can be verified by the existing tests. Also datalist will stop at tick marks.
Updated default theme to paint the slider thumb in a different step. This was done by splitting the thumb into a separated group.
