interactive examples)

* removed the special font renderer which was actually
the same as the normal one (one less renderer to update
the color of)
* added a special B_OP_COPY implementation for text, which
is in fact what the implementation was until now, so
just like on R5, you have to specify the correct low color
or you will see artifacts for the anti-aliased pixels
* implemented B_OP_COPY just like B_OP_OVER (only it draws
the low color too like it should). So all apps that
used B_OP_COPY to draw anything can continue to do so
without having to worry about the low color, it will
be anti-aliased against the actual background instead of
the low color (which made especially no sense when drawing
with the low color). Although this change makes it a bit
slower to use B_OP_COPY, Haiku is now much more compatible.

complete rework of the drawing_modes implementation... I achieved a speedup of 8 to 9 times, tested with text rendering. Believe it or not, but the Haiku text rendering is now faster than R5 for B_OP_COPY at least. And there is quite some room for improvement yet. (faster text bounding box calculation, avoiding the double UTF8 conversion, etc)

now has a special version of B_OP_OVER for solid patterns as well, accelerated the alpha blending for B_OP_OVER.... these are the first shy steps of rewriting the drawing mode stuff... :-)
