// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
+// 2024-01-22: Added configurable PipelineMultisampleState struct. (#7240)
// 2024-01-22: (Breaking) ImGui_ImplWGPU_Init() now takes a ImGui_ImplWGPU_InitInfo structure instead of variety of parameters, allowing for easier further changes.
// 2024-01-17: Explicitly fill all of WGPUDepthStencilState since standard removed defaults.
// 2023-07-13: Use WGPUShaderModuleWGSLDescriptor's code instead of source. use WGPUMipmapFilterMode_Linear instead of WGPUFilterMode_Linear. (#6602)
