Better errorhandling for the fontengine on WINCE.

The CE fontengine only supports translations, scaled
Text would only work if its an isometric scale and would
require to create a new font from the old one. Rotations
and more aren't supported at all. The freetype fontengine
for CE supports this, so we give a warning that the font
might be rendered incorrect, but could render correct with
the freetype engine.
