TSdlGpuVertexBufferDescription

A record specifying the parameters of vertex buffers used in a graphics pipeline.

When you call TSdlGpuRenderPass.BindVertexBuffers, you specify the binding slots of the vertex buffers. For example if you called TSdlGpuRenderPass.BindVertexBuffers with a AFirstSlot of 2 and ANumBindings of 3, the binding slots 2, 3, 4 would be used by the vertex buffers you pass in.

Vertex attributes are linked to buffers via the BufferSlot field of TSdlGpuVertexAttribute. For example, if an attribute has a buffer_slot of 0, then that attribute belongs to the vertex buffer bound at slot 0.
