 // CHANGELOG
 // (minor and older changes stripped away, please see git history for details)
+//  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)
 //  2023-04-11: Align buffer sizes. Use WGSL shaders instead of precompiled SPIR-V.
 //  2023-04-11: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
