some new examples

link to new gui tutorial about visualizing deformations

getFirstPhysical -> getLastPhysical, so that the coloring gets made according
to the latest physical entity created instead of the first one.

Requested by philou; most interesting when creating physical groups on
existing meshes.

say explictly that LaTeX XXX part output is without text

reverting last change: it's nicer to always have the z axis pointing up

change y,-y to have the axes the same way as for x,-x and z,-z

don't optimize transfinite volumes!

trying to fix the transfinite volume bug introduced by the 'left' and
'alternate' transfinite surface changes made a while ago

fix stat print for pyramids

new shortcuts for alternative x, y, z views (still needs to be completed by dave)

forgot to indent these two

- the fltk m#@!er f*!@ers changed the way FL_CTRL/FL_META shortcuts
are treated on the Mac. This patch forces FL_META (the "Apple key") for

- fix metis readme+configure info

update tetgen to latest version 1.3.4

upgrade triangle to version 1.6

prepare for 1.61

disable applyOptimizationPatterns for now

quick hack to get lighting of element edges (not perfect and rather slow
but good enough for me for now)

shorter intro

include metis in the free version since we now have Karypis' approval

tweak automatic polygon offset check

make "BoundingBox{x,X,y,Y,z,Z}" actually do what the documentation claims
it does
