Introduce the Qt graphics abstraction as private QtGui helpers Comes with backends for Vulkan, Metal, Direct3D 11.1, and OpenGL (ES). All APIs are private for now. Shader conditioning (i.e. generating a QRhiShader in memory or on disk from some shader source code) is done via the tools and APIs provided by qt-labs/qtshadertools. The OpenGL support follows the cross-platform tradition of requiring ES 2.0 only, while optionally using some (ES) 3.x features. It can operate in core profile contexts as well.

rhi: Unify handling of special cases for scissor and viewport rects With OpenGL a scissor (or viewport) rectangle is not allowed to have a negative width or height. Everything else is allowed. This is also the semantic we wish to keep for QRhiViewport and QRhiScissor. This raises some problems. For instance, when we do bottom-left - top-left rectangle conversion, the case of partially out of bounds rects needs to be taken into account. Otherwise, Qt Quick ends up in wrong scissoring in certain cases, typically when the QQuickWindow size is decreased so the content does not fit because that will then start generating negative x, y scissors for clipping (which is perfectly valid but the QRhi backends need to be able to deal with it) Then there is the problem of having to clamp width and height carefully, because some validation layers for some APIs will reject a viewport or scissor with partially out of bounds rectangles. To verify all this, add a new manual test, based on the cubemap one. (cubemap was chosen because that is an ideal test scene as it fills the viewport completely, and so it is visually straightforward when a scissor rectangle is moving around over it) Fixes: QTBUG-78702 Change-Id: I60614836432ea9934fc0dbd0ac7e88931f476542 Reviewed-by: Christian Strømme <christian.stromme@qt.io>

rhi: Add render-to-cubemap manual test What's more, demonstrate two types of rendering to a cubemap: one by one to each face, and by attaching all faces as color attachments in one go. Both are used by Qt Quick 3D in connection with shadows, so this proves that the same is possible to implement with QRhi.

rhi: Add support for 3D textures Supported on OpenGL (and ES) 3.0+ and everywhere else. Can also be a render target, targeting a single slice at a time. Can be mipmapped, cannot be multisample. Reading back a given slice from a 3D texture is left as a future exercise, for now it is documented to be not supported. Upload is going to be limited to one slice in one upload entry, just like we specify one face or one miplevel for cubemap and mipmapped textures. This also involves some welcome hardening of how texture subresources are described internally: as we no longer can count on a layer index between 0..5 (as is the case with cubemaps), simply arrays with MAX_LAYER==6 are no longer sufficient. Switch to sufficiently dynamic data structures where applicable. On Vulkan rendering to a slice needs Vulkan 1.1 (and 1.1 enabled on the VkInstance).
