Finds the chart point (i.e. within the chart's domain and range) represented by the given pixel coordinates, if
that pixel is within the chart region described by {@link #contentRectMinusAllMargins}. If the point is found,
the "dest"
argument is set to the point and this function returns true. Otherwise, this function returns false and
"dest" is
unchanged.
