Components may have multiple bounds and/or color child elements with state attributes, allowing for piecewise linear position/size/colour animation. Components may have a statemask attribute, allowing for things like using external images to draw a multi-segment LED/VFD display without requiring dozens of outputs for the individual lines or thousands of images for all possible states. (Texture caching still never releases anything, so MAME can still exceed the maximum number of textures, but that’s a separate issue.) Image components with alpha now blend over previously drawn components. Layouts have been changed to use yes/no for inputraw to match what's used for flipx/flipy. External layouts with 1/0 will still work, but complay.py will complain.
