What's your suggestion?

This new draw mode would be something in between Stretch and Repeat.

The way it would work is that the texture would be stretched to fill the entire bar (this is identical to Stretch when the bar is full), but the difference is when the bar's value is not full, it acts more like the Repeats, where the texture does not change its stretch to the new bar, instead it gets masked by the fill like the Repeats.

In essence, the current Stretch would be a Dynamic Stretch to change with the bar, while this new Stretch would be a Static Stretch that does not care about the bar value.
