add line stippling for 2d plots

removed unused Post.Scales option

if no mesh file name is specified, use the problem name to construct one

fix gcc warning

fix compile: iso c++ forbids variable-size arrays

small doc fix

add error check for discrete curves

if there is no selection in the option browser display general options

damn, fix division  by zero in Progress() if we have less than 10 nodes

duplicata -> alias

better subdivision scheme for drawing scalar hexahedra (with edges matching
on opposite faces)

make center/right-align work for scales and 2d-plots, too

init val of NbTimeStep should be 1, not 0

- fixed double free in case there is an error in tSprintf

- new StrRelative command

- small demo on how one can add a generic title to a plot using
