I am using mypy as the type checker which complains when I am trying to add a tuple to an ImVec2:

demo.py

from imgui_bundle import imgui

ImVec2 = imgui.ImVec2


v = ImVec2(0, 0) + (1, 1)

Run type check:

> mypy demo.py
demo.py:6: error: Unsupported operand types for + ("ImVec2" and "tuple[int, int]")  [operator]
Found 1 error in 1 file (checked 1 source file)

The current implementation uses a generic protocol for both ImVec2 and ImVec4.
It can not express the fact that, for example, we can add a 2-item tuple to ImVec2 but not to ImVec4,
and we can add a 4-item tuple to ImVec4 but not to ImVec2.

By using separate protocols, we can be more precise about the types that those math operators supports
