Khaled Hosny 00060d99f3 [hb-cairo] Silence warning when building with FreeType
In file included from ../util/hb-view.cc:33:
In file included from ../util/view-cairo.hh:32:
../util/helper-cairo.hh:102:7: warning: variable 'cairo_face' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
  if (use_hb_draw)
      ^~~~~~~~~~~
../util/helper-cairo.hh:129:64: note: uninitialized use occurs here
  cairo_scaled_font_t *scaled_font = cairo_scaled_font_create (cairo_face,
                                                               ^~~~~~~~~~
../util/helper-cairo.hh:102:3: note: remove the 'if' if its condition is always true
  if (use_hb_draw)
  ^~~~~~~~~~~~~~~~
../util/helper-cairo.hh:101:32: note: initialize the variable 'cairo_face' to silence this warning
  cairo_font_face_t *cairo_face;

                                = nullptr

We know that cairo_face will always be assigned since use_hb_draw will
always be true, but the compiler does not know that.

Matthias Clasen 4816be9ab5 Work around cairo limitations
If we just draw an image, cairos recording surface
complains that it is unbounded. Its not true of course.

To make things work, clip to the extents.

Matthias Clasen ecd7420456 Debug spew
To get a dump of the hb-paint callbacks,
set HB_PAINT_DEBUG=1 when running hb-view.

For now, leave this code in place, since it
comes in handy for various debugging.
