* the vertex buffers. For example if you called SDL_BindGPUVertexBuffers with
* a first_binding of 2 and num_bindings of 3, the binding indices 2, 3, 4

*
* Vertex attributes are linked to bindings via the index. The binding_index
* field of SDL_GPUVertexAttribute specifies the vertex buffer binding index
* that the attribute will be read from.
* Vertex attributes are linked to buffers via the buffer_slot field of
* SDL_GPUVertexAttribute. For example, if an attribute has a buffer_slot of 0,
* then that attribute belongs to the vertex buffer bound at slot 0.
