Summary0001598: Increase performance by rendering primitives front to back
Description

We experimented with this in NoesisGUI 2.1, using the zBuffer to discard non-visible pixels but we didn't find a good way to make this faster in all scenarios. The fact that our PPAA algorithm is using alpha-blending is not helping. Also increasing the size of dynamic geometry to include a fake z coordinate in every vertex was making performance worse. The alternative was disabling our batching algorithm, but this is not definitely a good idea in older APIs like D3D11 or OpenGL (probably good on Vulkan or D3D12).

We need to investigate this more.
