Fixes #188712

Honors the enable argument in RenderPass.setDepthWriteEnable. The native binding InternalFlutterGpu_RenderPass_SetDepthWriteEnable ignored its argument and always set depth_write_enabled to true, so RenderPass.setDepthWriteEnable(false) was a no-op and depth writes could not be disabled for any Flutter GPU draw.

Pre-launch Checklist

…able

InternalFlutterGpu_RenderPass_SetDepthWriteEnable ignored its `enable`
argument and always set depth_write_enabled to true, so
RenderPass.setDepthWriteEnable(false) was a no-op and depth writes could
not be disabled. Unsorted overlapping translucent draws (for example one
instanced draw of overlapping billboards) then self-occluded instead of
blending.

Honor the argument, and add a gpu_unittests regression test.

Fixes flutter#188712

Code Review

This pull request fixes a bug in InternalFlutterGpu_RenderPass_SetDepthWriteEnable to ensure it honors its boolean argument instead of always enabling depth writes. It also adds a regression unit test to verify this behavior. The feedback suggests organizing the include directives in the new test file to comply with the Google C++ Style Guide by grouping library headers before project headers and directly including the header defining fml::MakeRefCounted.

Comment thread engine/src/flutter/lib/gpu/render_pass_unittests.cc Outdated
Order the includes per the Google C++ style guide (gtest before fml).
fml::MakeRefCounted is declared in fml/memory/ref_ptr.h, so that include
is kept and ref_counted.h is not needed.
