the object is a GenCxxObject just like those from CustomTargets, we only need to get the generation right

This change should allow handling double-quation inside quoted cells
correctly.

Always enabled, as this runs for me with an overhead in the range of
measurement error (in tail_build):

There already is a dependency from the library to the package, so this
dependency should not be necessary.
Furthermore, the command is executed spuriously always, because the .done
file is always newer than the generated files.

This reverts commit 6c8a7e0e.

Doing this explicitly is unnecessary because make does it automatically.
Also, make will pass --jobserver-fds, which happens to match in
findstring as well.

We get more similar linking errors elsewhere anyway. We would need a
more generic fix. As for now, just apparently not possible to build
with the LLVM g++ from Xcode 4. Use g++-4.2 / gcc-4.2 if you want ot
use Xcode 4. But note that for Xcode 4.2, you might need to do:

ln -s i686-apple-darwin10 /Developer/SDKs/MacOSX10.6.sdk/usr/lib/gcc/i686-apple-darwin11

This reverts commit f3e10529.

i.e. font names are often typically in English, so fairly useless
to take the English name to preview what effect the font will have
in a CTL/CJK script.

More languages and scripts need to be added, but this should be
sufficient to bootstrap this up

it seems that the heuristic to trigger the inflate hack from frob is both wrong in the code ( my fault ) and additionally doesn't always hold true ( found a document where the heuristic is triggered falsely ) So. removing that heuristic entirely for now

Seems the graphic load code is stupid and not using the path name /
file extension to guess file type, but only "magic byte" detection.
Giving filter framework the path now, so that .svg actually loads.
