a drag and drop source or target: a SetNextWindowPos() call won't be overriden. (#6973)
- Style: added PushStyleVarX(), PushStyleVarY() helpers to modify only one component of a ImVec2 var.
- Fonts: made it possible to use PushFont()/PopFont() calls accross Begin() calls. (#3224, #3875, #6398, #7903)
- Backends: GLFW: added ImGui_ImplGlfw_Sleep() helper function because GLFW does not
provide a way to do a portable sleep. (#7844)
- Backends: SDL2, SDL3: ignore events of other SDL windows. (#7853) [@madebr, @ocornut]
- Backends: SDL2, SDL3: storing SDL_WindowID inside ImGuiViewport::PlatformHandle instead of SDL_Window*.
- Backends: SDL3: Update for API changes: SDL_GetGamepads() memory ownership logic was reverted back
by SDL3 on July 27. (#7918, #7898, #7807) [@cheyao, @MattGuerrette]
- Backends: GLFW: passing null window to glfwGetClipboardString()/glfwSetClipboardString()
since GLFW own tests are doing that and it seems unnecessary.
- Backends: SDL2, SDL3, GLFW, OSX, Allegro: update to set function handlers in ImGuiPlatformIO
instead of ImGuiIO.
- Examples: GLFW (all), SDL2 (all), SDL3 (all), Win32+OpenGL3: rework examples main loop
to handle minimization without burning CPU or GPU by running unthrottled code. (#7844)
