Subject: [PATCH] Improved Voodoo performance when using CPU threaded rendering

Improves 3dfx Voodoo frame rates by 3 - 8% (sometimes slightly less or more) depending on the game. This applies to the core options 'Software Multi Threaded (default)' and 'Software Multi Threaded, low quality'.

Many game test results can be viewed [here.](https://github.com/schellingb/dosbox-pure/issues/519#issuecomment-2438388162)
