Use MargeWithBoundingBox

Slightly change the way we compute the bounding box during OpenFile
(not MergeFile), so that opening a file containing both a
geometry/mesh and a view works as expected.

Bump version number to 1.40

Add some indent directives

some indent stuff

Fix all "uninitialized var" gcc warnings, even if they are bogus.

Specify limitations for transfinite meshes explicitly

Use correct callback for transfinite volume definitions

Fix some dependencies + enable GSL (so that more people test it).

fix poor english

pretty print

typo

add "make source-nonfree"

rename some variables to avoid confusion

fix MAX_NEWTON_DIM

add gsl_check in batch mode, too

Re-add missing paragraph

Fix some problems in gsl minimization algo. Still reports errors in
some cases...

New gsl error handler

specify GSL version + GPL

cleanup

Print more informative messages for Triangle, GSL, etc.

Fix typo in Nicolas' name

cosmetic changes

bump version number to 1.39

fix dependencies

This is a pretty big commit.

- The Numerical Recipes routines have been moved to their own
subdirectory: NR/

- These routines are now completely optional. Configure will
determine if they have to be compiled in (if it's a non-free version
of Gmsh) or if we should use the GSL routines instead.

- The GSL routines are there. Well, sort of. The SVD stuff works
great, but the minimization routines still need more work. The whole
infrastructure is there, though: we can already compile a fully GPL
compliant version of Gmsh by removing the NR subdirectory (or by
specifying --enable-gsl to configure).

- I also simplified the options passed to the compiler (OPTIM and
FLAGS).

That's all for today folks...

Add comment for LITTLE_ENDIAN problem

Don't use LITTLE_ENDIAN, it may be defined on Macs and cause the
colormap problems. Define and test _BIG_ENDIAN instead.

Change NODLL to _NO_DLL
