Subject: Fl_Cairo_Graphics_Driver: fix issues in string width computations
 when scaling applies.

The implemented approach is to create and use the pango_layout_ object only relatively
to an unscaled cairo context. With this, the pixel width of a drawn string equals
the sum of the widths of its characters.
