For/EndFor loop corrections  exposed small bug here :-)

Don't optimize Gmsh.tab.o: on many architectures, g++ -O2 generates
assembly code too large to be addressed correctly. This will hopefully
fix the build problems reported on ppc.

don't need UpdateViewsInGUI in parser anymore

better test for invalid For/EndFor loops

Don't update the views in the GUI directly after each view is created.
Instead, wait until the whole file is read. This speeds up the creation
of the interface dramatically when we have a large number of views in
a single file. (In my code I routinely merge around 1000 views
in a single file to do animations; with this patch, the GUI creation
time goes from 30 seconds to less than 1 second.)

simpler solution to 2D primitive sorting problem

translate all 2D objects before drawing them: this is the easiest way
to get GL2PS to put them "in front"

use the alignement capabilities of GL2PS for TeX output (this allows gmsh to
create nicely aligned labels even with equations)

fix tex output in gl2ps for large scenes

typo

optimize jpeg coding to produce smaller files (patch from Dave Coffin)

last missing routine (to combine text strings time steps). ouf.

- changed the Shift+XX menubar shortcuts into either Ctrl+XX or
  Ctrl+Shift+XX (we shouldn't use Shift+XX shortcuts in the menubar,
  in particular on Mac, where the shortcuts conflict with input
  text fields)

- exchanged the meaning of Ctrl+s and Ctrl+Shift+s, as this is what
  most people expect

by convention, for 2d strings, assume that a coord value > 99999 means the
center of the window

removed unused extern

add title

update docs

- cleaned up + generalized font selection
- generalized Plugin(Annotate) to allow font style selection for
  each text fragment
- fixed bug in per-view color selection

don't require gl2ps

missing line_width/point_size calls

cut & paste buglet

add missing combine_strings in combine_space (still need to implement
the string combination in combine_time)

clarify help

forgot to recompute the bbox

small bug fix: smooth() did not recompute TimeStepMin/Max

add a comment around a test copied as-is from the old Gradient plugin

merged Plugin(Lambda2) and Plugin(Gradient) in a single plugin, so that
we free up Plugin(Gradient) for future use

fix txt output with new versions of make info

- plugin callbacks now draw their stuff until run/cancel is executed (so we
  manipulate the scene with the additional data displayed)
- made plugin code much shorter
- simpler defaults for StreamLines, CutGrid and Evaluate

draw points instead of grid
