Weight Paint - Zero Weights "Active" should be default.

The Zero Weights option should be set to "Active" by default for better readability.

I saw many people struggle with weight painting just because they can't tell where the weight paint starts and stops. Since near 0 weights have the same color as 0 weights. This also makes it hard to spot if you accidentally painted where you didn't want to.

Default look in 3.6.1 as you can see the user can't tell if the whole mouth is painted or not.

Proposed new default. Instantly you can tell where are 0 weights and where are weights close to 0.
