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.
Do not clean polygons that are created for different faces not connected with current shape.
Remove old code producing additional points for BSpline curves due to fix#24959.
