Run clang-format over all project C/C++ source and header files
(.c, .cpp, .cc, .h, .hpp, .hh, .m, .mm) under app/ and tests/.
Non-source files (svg, qm, qrc, etc.) were not touched.
- Add shared UBO layout across vertex + fragment stages so vertex
uniforms like ove_mvpmat compile and bind correctly.
- Rewrite uniform extraction/injection to avoid corrupting the UBO
block and to keep explicit sampler bindings stable.
- Make the UBO and sampler descriptor bindings visible to both vertex
and fragment stages.
- Add layout locations for vertex varyings (ove_texcoord) and fragment
inputs so SPIR-V generation succeeds.
- Extend TransitionImageLayout() to cover all layout pairs used by
upload/download/clear/blit.
- Add subpass dependencies to the cached render pass and leave
destinations in SHADER_READ_ONLY_OPTIMAL after Blit().
- Move descriptor allocation before command recording and abort cleanly
if allocation fails; switch Blit() to the persistent linear sampler.
- Add a gtest that creates a Vulkan backend, uploads a red U8 RGBA
texture, blits through the default pass-through shader, and verifies
the downloaded pixel is red. This test passes on the current system.
ctest passes 4/4; DynamicRenderBackend.* passes 3/1 (Vulkan fallback
skipped because Vulkan is available).
- Extract libolive-rendercore static library to minimize backend link boundary.
- Add DynamicRenderer adapter with C ABI (oakgl/oakvulkan shared libs).
- Make OAK_ENABLE_DYNAMIC_RENDER_BACKEND default ON with OpenGL fallback.
- Implement VulkanRenderer prototype (textures, shaders, UBO blit, readback).
- Add backend-neutral viewer readback path (offscreen -> QImage -> QPainter).
- Refactor PluginRenderer to be renderer-agnostic; OFX plugins fall back to CPU
path on non-OpenGL backends while preserving OpenGL render path.
- Add Renderer::AttachOutputTexture/DetachOutputTexture and C ABI forwards.
- Update docs/zh/render-backend-dynamic-plan.md for Phase 3/4/5.
