How Frames Work in Animatica

• The from image is a single tall image made of frames stacked one above another, each w wide and h tall. Frame 0 is at the top, frame 1 below it, and so on.
• Each tick the mod advances the animation and draws the current frame onto the target texture at (x, y).
• With interpolate=true, the mod blends between the current and next frame based on how far through the frame's duration it is, producing smooth motion instead of a slideshow.
• The animation loops continuously. Using tile.<n> you can make it revisit frames (for example 0, 1, 2, 1 for a back-and-forth pulse).

Because everything is driven by the source strip and the .properties timing, an animation can be as short as two frames (a simple blink) or a long, smoothly-interpolated sequence.
