Blender Version: 3.1.2
**Short description of error**
To my knowledge, the term Render Border is (or will be) deprecated. It used to be what is now called Render Region and had the same meaning. Some operators still use that term though.
**Exact steps for others to reproduce the error**
in 3DView, hit F3 and type "border". There are 5 results:
- in Preferences > Interface, enable "Developer Extras"
- "Zoom to Border": This one is unrelated, as it doesn't refer to Render Regions. Could still use the term Region anyway, though border is fine to me here.
- "Reset Render Border": should definitely use the term Region
- "Clipping Region": unrelated to Render Region, but python operator label uses "border" while the UI name uses "Region" (API compatibility reasons?)
- "Set Render Region": same here, python label uses "border", UI name uses "Region".
Keeping the legacy term in the API label makes sense (prevents add-ons from breaking), though eventually it should be consistent with the UI. At the very least the UI names should be consistent.
Note: Changing to "Region" was a great decision imo, as its meaning is much more explicit than Border.
