new (probably temporary) gmsh/mesh/createEdges and gmsh/mesh/createFaces (until we provide a facility to simply create and store mesh edges/faces as elements)

only return entities in output maps if the entities are bound: otherwise, when entities are unmodified by the boolean operation but are deleted, we would return non-existing entities (cf #1154)

put "My solver" widgets in the main Solver menu + show how to have a "3D" button for actions instead of the standard text

new "Aspect" attribute for string variables: if equal to "Button", draw a standard button instead of a simple clickable text

fix error in documentation: node and element tags in MSH4 are still ints (not size_t) in $NodeData, $ElementData and $ElementNodeData (cf. #1157). The switch to size_t is planned for a future revision of the MSH format, at the same time as the restructuring of the post-processing IO format to make it more efficient.

bind highest dim entities after boolean operation only if explicit tag is given; when preserveNumbering is not set bind all the entities, as when preserveNumbering is set (cf. #1154)

Automatic isotropic mesh size field

See merge request !388

recursive visibility/color now also applies changes to embedded entities; test clang-tidy modernize-use-auto

test FLTK_ABI_VERSION instead of FL_*_VERSION: the change introduced in FLTK 1.3.5 is ABI incompatible with FLTK 1.3

this should fix #1144

when the cross cannot be computed for a surface, add a single point (the center of the bounding box) instead of nothing, so that we still have a location to draw e.g. the label

new -noenv and -nolocale to prevent Gmsh from modifying the environment or the locale at startup (cf. #1142)

Add regular tutorials (1-21) to cookbook
