Windows Close and Collapse Buttons.

- Misc: Fixed ImVec2 operator[] violating aliasing rules causing issue with Intel C++
|

compiler. (#6272) [@BayesBug]
|

- IO: Added io.AddMouseSourceEvent() and ImGuiMouseSource enum. This is to allow backend to

specify actual event source between Mouse/TouchScreen/Pen. (#2702, #2334, #2372, #3453, #5693)

- IO: Fixed support for calling io.AddXXXX functions fron inactive context (wrongly
|

advertised as supported in 1.89.4). (#6199, #6256, #5856) [@cfillion]
