- 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@167 bbaffbd6-741e-11dd-a85d-61de82d9cad9

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)

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


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@154 bbaffbd6-741e-11dd-a85d-61de82d9cad9

git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@150 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 enable the "material allowance" control only if ODE and the DropCutter is enabled (the others need to be implemented)

 derive the ToroidalCutter shape from the CylindricalCutter (not perfect, but it works)
 prevent all impossible combinations of tool and path settings by disabling the respective controls
