Sets blend constants for draw list, blend constants are used only if the graphics pipeline is created with [constant DYNAMIC_STATE_BLEND_CONSTANTS] flag set. Rendering device type does not match any of the other enum values or is unknown. Rendering device is an integrated GPU, which is typically [i](but not always)[/i] slower than dedicated GPUs ([constant DEVICE_TYPE_DISCRETE_GPU]). On Android and iOS, the rendering device type is always considered to be [constant DEVICE_TYPE_INTEGRATED_GPU]. Rendering device is a dedicated GPU, which is typically [i](but not always)[/i] faster than integrated GPUs ([constant DEVICE_TYPE_INTEGRATED_GPU]). Rendering device is an emulated GPU in a virtual environment. This is typically much slower than the host GPU, which means the expected performance level on a dedicated GPU will be roughly equivalent to [constant DEVICE_TYPE_INTEGRATED_GPU]. Virtual machine GPU passthrough (such as VFIO) will not report the device type as [constant DEVICE_TYPE_VIRTUAL_GPU]. Instead, the host GPU's device type will be reported as if the GPU was not emulated. Rendering device is provided by software emulation (such as Lavapipe or [url=https://github.com/google/swiftshader]SwiftShader[/url]). This is the slowest kind of rendering device available; it's typically much slower than [constant DEVICE_TYPE_INTEGRATED_GPU]. Represents the size of the [enum DeviceType] enum.
