0024500: Sudden exit of DRAW after multiple execution of test in cycle

Test commands for #23952 refactored to:
- avoid interaction with Tcl interpreter from thread functions (fixes sudden crash)
- get shapes outside of the thread functions (keeping only code being tested inside)
- run 100 threads instead of 2 (increases chance for data race to exhibit if present)

Linux compilation problems fixed.
