MoonPowerandGitHub 413c8817d4 Merge branch 'ocornut:master' into sdl_cpu 2026-03-13 14:50:16 +01:00
moonpower 5ae4be2b5f Refactor SDL surface backend for improved quad rendering and performance 
- Introduced a new structure ImGui_ImplSDLSurface3_Quad to represent quads.
- Added functions to detect quads and check for constant colors and linear UVs.
- Enhanced rendering functions to utilize quad detection for faster rendering paths.
- Updated the rendering logic in ImGui_ImplSDLSurface3_RenderDrawData to leverage the new quad rendering capabilities.
- Optimized Makefiles and build scripts to include optimization flags for better performance.

moonpower 2f2b8a1226 Add SDL3 surface backend for ImGui example 
- Created imgui_impl_sdlsurface3.h and corresponding implementation file.
- Added Makefile for building the SDL3 surface example on Linux and macOS.
- Included README.md with build instructions for Windows, Linux, and macOS.
- Added build script for Windows (build_win32.bat) and Visual Studio project files.
- Implemented main application logic in main.cpp to demonstrate ImGui with SDL3 and surface rendering.

MaciejDziubanandocornut decb5cdf10 Backends: Vulkan: added ImGui_ImplVulkan_PipelineInfo::ExtraDynamicStates. (#9211) 
This new setting allows an application to force the pipeline created by vulkan backend to specify more dynamic states than just default viewport and scissor.
It is useful e.g. when using draw list callbacks, e.g. adding VK_DYNAMIC_STATE_COLOR_BLEND_EQUATION_EXT to be able to use vkCmdSetColorBlendEquationEXT inside callbacks.

Yan Pujanteandocornut e92820db2a Backends, Examples: removed Emscripten < 4.0.10 support. Removed IMGUI_IMPL_WEBGPU_BACKEND_WGPU. (#9281, #8381) 
- This commit removes the option of using -sUSE_WEBGPU=1 from CMake and make
- Compiling with a version of Emscripten >= 4.0.10 will work the same way as it was before
- Compiling with a version of Emscripten < 4.0.10 will print an error message and abort the build (in the case of CMake)
- Since there can only be 1 implementation for the backend in the case of Emscripten, this commit cleans the code accordingly

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.
