/**
* The buffer containing the data for the render model.
*
* Description
*
* {@link XrRenderModelBufferFB} is used when loading the binary data for a render model. {@link XrRenderModelBufferFB} must be provided when calling {@link FBRenderModel#xrLoadRenderModelFB LoadRenderModelFB}.
*
* Valid Usage (Implicit)
*
*
* - The {@link FBRenderModel XR_FB_render_model} extension must be enabled prior to using {@link XrRenderModelBufferFB}
* - {@code type} must be {@link FBRenderModel#XR_TYPE_RENDER_MODEL_BUFFER_FB TYPE_RENDER_MODEL_BUFFER_FB}
* - {@code next} must be {@code NULL} or a valid pointer to the next structure in a structure chain
* - If {@code bufferCapacityInput} is not 0, {@code buffer} must be a pointer to an array of {@code bufferCapacityInput} {@code uint8_t} values
*
*
* See Also
*
* {@link FBRenderModel#xrLoadRenderModelFB LoadRenderModelFB}
