- ImDrawList: AddCircle, AddCircleFilled(): Tweaked default segment count calculation to honor MaxError
with more accuracy. Made default segment count always even for better looking result. (#3808) [@thedmd]
- ImDrawList: AddCircle, AddCircleFilled(): New default for style.

- Backends: OpenGL, Vulkan, DX9, DX10, DX11, DX12, Metal, WebGPU, Allegro: Rework blending equation to
preserve alpha in output buffer (using SrcBlendAlpha = ONE, DstBlendAlpha = ONE_MINUS_SRC_ALPHA consistently
accross all backends), facilitating compositing of the output buffer with another buffer.
