License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
Handle classes now use 0 as invalid value for pointer instead of custom (and platform-dependent) value like 0xfefd0000.
Compiler macros UndefinedHandleAddress and _OCC64 are eliminated.
Methods OSD::Handler(), OSD::SegvHandler(), OSD::WntHandler() were made static
Type cast were removed when pointer on signal handler function is used
Enumeration OSD_Signal removed
Possibility to break DRAW commands by user break (Control-C) is implemented as follows:
- Treatment of Control-C (SIGINT signal) on UNIX in OSD::SetSignal() is made coherent with Windows implementation: instead of attempt to raise exception (simulated by longjump, does not work anyway), signal handler just sets a flag which can be later checked by OSD::ControlBreak()
- Call to OSD::ControlBreak() is added to common entry point for OCCT DRAW commands; this causes command interruption if Control-C has been pressed before its start.
- Command "dbreak" added allowing to check Control-Break status from Tcl script (raises Tcl exception if break was signaled)
- Command "dversion" added printing information on OCCT version, used build options, compiler, etc.
- Test system modified to properly handle and report user breaks and add version info in the summary log
