Fixed assertion when transitioning from an active ID to another within a group, affecting ColorPicker (broken in 1.62). Made ActiveIdIsAlive track the actual ID to avoid incorrect polling in BeginGroup/EndGroup when the ID changes within the group. (#2023, #820, #956, #1875).

- Misc: Added ImGuiMouseCursor_Hand cursor enum + corresponding software cursor. (#1913, 1914) [@aiekick, @ocornut]
- Misc: Tweaked software mouse cursor offset to match the offset of the corresponding Windows 10 cursors.
- Made assertion more clear when trying to call Begin() outside of the NewFrame()..EndFrame() scope. (#1987)
- Fixed assertion when transitioning from an active ID to another within a group, affecting ColorPicker (broken in 1.62). (#2023, #820, #956, #1875).
- Fixed PushID() from keeping alive the new ID Stack top value (if a previously active widget shared the ID it would be erroneously kept alive).
- Fixed horizontal mouse wheel not forwarding the request to the parent window if ImGuiWindowFlags_NoScrollWithMouse is set. (#1463, #1380, #1502)
