ID2D1RenderTarget::PushAxisAlignedClip/PopAxisAlignedClip used to clip the region (with wxGraphicsRenderer::Clip) and ID2D1RenderTarget::PushLayer/PopLayer used to rendering to the transparent layer (with wxGraphicsRenderer::BeginLayer) are non independent but have to be used in the controlled sequences: "A PushAxisAlignedClip and PopAxisAlignedClip pair can occur around or within a PushLayer and PopLayer, but cannot overlap" (and of course finally each Push* call must have a matching Pop* call). To control the sequence of access to the AxisAlignedClips and Layers there is implemented a wxStack data member holding Clips/Layers parameters which reflects a physical stack of respective Clips/Layers in ID2D1RenderTarget. This way we know in which order to pop and what to pop from ID2D1RenderTarget stack if there is a need to do so. Closes #17590

wxWidgets is a free and open source cross-platform C++ framework for writing advanced GUI applications using native controls.
wxWidgets allows you to write native-looking GUI applications for all the major desktop platforms and also helps with abstracting the differences in the non-GUI aspects between them. It is free for the use in both open source and commercial applications, comes with the full, easy to read and modify, source and extensive documentation and a collection of more than a hundred examples.
