automatically add the default file extension during "save" operation, if the entered filename does not contain a dot

hide the previous toolpaths after generating a new one, if there was only one visible before (this should be less confusing)
display the number of current toolpaths in the toolpath tab label

git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@178 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 * export multiple toolpaths to a single gcode file
 * sort toolpaths arbitrarily
 * deleted a toolpath from the list

git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@176 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 * tool-id (e.g. "T1")
 * allow to use general IO streams instead of a file output
 * allow to skip the "M2" command ("end program") for multiple assembled toolpaths


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@175 bbaffbd6-741e-11dd-a85d-61de82d9cad9

added basic support for multiple toolpaths

tool id written by the gcode exporter is configurable (not used for now)


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@172 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 - pycam did not start on Windows
 - PyODE occasionally exposed a threading bug ("Exception exceptions.KeyError: (...,) in 'ode.collide_callback' ignored") preventing ODE from detecting any collisions
  - this rarely happened with the "Finish" processing template
  - this usually happened with the "Rough" processing template
Thus the threading code is gone again. Instead there will be lazy GUI updates via gtk.main_iteration in the draw_callback function.


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@171 bbaffbd6-741e-11dd-a85d-61de82d9cad9

added example key handler for 3d window


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@170 bbaffbd6-741e-11dd-a85d-61de82d9cad9

closing the main window cancels a potentially running multi-threaded calculation

prevent the DropCutter from going down to zero, if the model exceeds the height of the bounding box (introduced by the new dropcutter code)
 - this (obviously) violates the boundary box limits


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@166 bbaffbd6-741e-11dd-a85d-61de82d9cad9

changed the gcode exporter code to allow a specific definition of the safety height (instead of previous "max(safetyheight, homeheight, startz)")
moved "startz" offset (based on the configured measurement unit) from SimpleGCodeExporter to the Gui code to allow more control
slight beautification of the gcode exporter code (added spaces between operators and after commas - according to PEP 8)

 added requirement GTK to the config options


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@159 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 implement non-interactive mode for GTK interface
 renamed function "save" in SimpleGui.py to "save_toolpath"
 small cleanups


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@158 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 fixed remaining reference to INFINITE (now: safe height)


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@157 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 make sure that the path generators never get stuck in in infinite loop caused by floating point inaccuracies
 define a maximum recursion depth (20) for the PushCutter algorithm (i.e. maximum precision = 1/(1^20) of bounding box width)


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@156 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 fixed a small nasty bug, that occours in the DropCutter for small values of "material allowance"
 
 Description: ODE did not take the "extended" drill shapes into account, when deciding, if
 collisions are possible. Thus the collide callback was never called.


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@155 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 use a calculated "safe height" instead of "utils.INIFINITE" for a boundary limit failure in DropCutter (otherwise it looks like a bug)
  - issue a warning once
