Added possibility to define patterns that must be present in the test log, so that test is considered OK only if all these patterns are found.
New REQUIRED statement is introduced for that, documented in dox/dev_guides/tests/tests.md.
Removed all uses of decho and dlog commands, added REQUIRED where necessary.
Command xdistcs is modified to output to Tcl instead of cout, and extended to report errors and warnings if distances are greater than tolerance (directly, instead of complex post-processing on Tcl level).
DEBUG mode for TODOs was removed (we should have no deviations in Debug mode).
Corrected indentation in DrawResources/TestCommands.tcl
HTML log will now highlight TODO statement causing IMPROVEMENT status, or REQUIRED statement causing FAIL, by corresponding color.
asymmetrical check in Standard_Boolean IntCurve_IntPolyPolyGen::findIntersect was changed to symmetrical.
fix wrong calculation of approx parameter on curve for last polygon segment
Added test case bugs/modalg_5/bug24035
Modified TODO in "de" test cases because there are small differences with old behaviour
Modified test case heal/split_closed_faces/G5 because of corrections in intersector's behavior, which lead to changes in checkshape
