Follow cl-gfx 425267a: the types functions declare
Formats and Types lists the new types data-vector, data-element-type
and bind-group-index. The API reference and the pages on passes and
textures give the ranges of counts, indices, offsets, sizes, mip levels
and depths, and Errors and Validation shows how SBCL words a refused
argument, which replaces the message for an unknown element type.
Follow cl-gfx 02db471: Vulkan 1.4, its features, and surfaces destroyed at once
A device needs Vulkan 1.4, whose devices have every feature cl-gfx
enables on all: the optional features are :GEOMETRY-SHADERS,
:TESSELLATION-SHADERS, :FLOAT64, :MULTISAMPLE-STORAGE-TEXTURES and
:VERTEX-STORES, and cube arrays and anisotropic samplers need none. A
multisampled texture may be a :2D-ARRAY, and DESTROY-SURFACE waits for
the GPU and destroys the surface at once, between frames.
