9bd5d8a240 Backends: misc renaming of locals. Use 'draw_list' instead of 'cmd_list'. Avoid using 'ctx'. 
This is likely to trigger merging issues. If it does, best to always get "theirs" and rename in there.

055e71518e Backends: clear bits set in io.BackendFlags on backend Shutdown(). Clear BackendPlatformName. (#6334, #6335)

e816bc6723 Merge misc changes from docking branch to reduce small drift. 
In particular:
- imgui.cpp : move UpdateInputEvents() higher in NewFrame() to match docking + update RenderMouseCursor() to match.
- imgui_draw.cpp: ImDrawList::_ResetForNewFrame() change from c807192ab
- Backends: SDL2. Add MouseWindowID + change SDL_CaptureMouse() test to match docking branch. Not strictly necessary but aimed at reducing drift because we go on and fork this file.
+ moved responsability of checking valid names to TabBarGetTabName() to simplify both branches.

4cec3a0467 Backends: support for multiple imgui context with little testing (#586, #1851, #2004, #3012, #3934, #4141) 
I believe more renderer backends should work. GLFW/Win32/SDL/Vulkan probably have many issues.

8ced41570e Backends: DX9: explicitely disable texture state stages after >= 1. (#4268) 
imgui only uses texture stage state for stage 0
But any state set in stages >= 1 will affect rendering
Set stage 1 COLOROP to DISABLED, to deactivate stages >= 1
