Cast: Speed up some long running tests in DEBUG mode.

Cast: Speed up some long running tests in DEBUG mode.

These tests iterate over 10000 frames, and with debug mode
being 13+ times slower than release mode, this ends up taking
too long. Hopefully we won't loose much coverage by reducing
the number of iterations in debug mode.
