Option(?) to stack temp and current HP

[mkahvi]

Is your feature request related to a problem? Please describe.
Temporary HP in Pathfinder 1 at least works as a buffer on top of normal health and count as normal health for almost all things relating to health (including unconsciousness from nonlethal damage and such). It thus makes sense that it would count as buffer on Top of the HP.

Currently this stacking is ignored for nonlethal damage exceeding base HP instead of combination of base HP + temporary.

Describe the solution you'd like
Extend the health bar with temporary hit points instead of overlaying it. Handle the actual effective HP correctly.

Additional context
Here for example, effective HP is 35+20=55, which is definitely above 45 nonlethal, yet it is rendered as if it was below:

I second this for D35E system.
