Laurenz Altenmüllerandocornut fbe973a8d0 Cast this to (void*) in zero-clearing memset calls to fix -Wnontrivial-memcall (#9247, #8295, #8129, #8135) 
Clang 20+ warns on memset(this, ...) for non-trivially copyable types via -Wnontrivial-memcall.
Should separately investigate -Wnonontrivial-memaccess vs -Wnonontrivial-memcall.

ocornut e674f57bb6 Backends: SDL3: Fixed an issue with missing characters events when an already active text field changes viewports. (#9054) 
Always use SDL_GetKeyboardFocus().
(tried to defer ImGui_ImplSDL3_PlatformSetImeData() processing for when OS-window is available but it didn't actually work because we don't systemetically OS-focus new viewports and SDL3 only sent characters to keyboard focused window.)
