There's a Video Digitiser for the BBC Micro I'd like to emulate at some point, but we don't yet support any kind of video input. Would implementing a bitmap_image_device be a suitable compromise to allow emulating such devices?

With a bitmap_image_device you'd be able to provide a bmp image for the emulated device to capture. Waste of time or worthwhile?
