[Substance] Slow response for column selection on massive-data JTable

[goodwilling]

Version of Radiance (current development is 3.0-SNAPSHOT): 2.0

Sub-project (Neon, Trident, Substance, Flamingo, ...): Substance

Version of Java (current minimum is 9): 8

Version of OS: Windows, Linux, (not tested on MacOS)

The issue you're experiencing (expected vs actual, screenshot, stack trace etc)

The mouse response becomes very slow when switching between columns of a JTable that has more than 50000 rows. The response is normal if using the Windows or metal look and feel.

I can't reproduce this in the test app. SubstanceTableUI has special case for large tables - when there's more than 500 cells, all animations are disabled.

Would it be possible to get a small, standalone and complete class that reproduces what you're seeing under the latest 3.0-SNAPSHOT?

Missed the column selection part. I see that it is indeed slow.
