ISSUE-2307: SMIL calcMode="paced" and animation of viewBox is underspecified
SMIL calcMode="paced" and animation of viewBox is underspecified
- State:
- RAISED
- Product:
- SVG 2
- Raised by:
- Jonathan Watt

- Description:
- To be able to do paced animation of viewBox, the specification needs to specify how the "distance" between viewBox rects is to be calculated. Mozilla currently takes the square root of sum of the squares of the distances between the corresponding sides of the rects. We use the edges rather than x, y, width and height, because this is necessary in order for the "distance" result that we calculate to be the same for a given change in the left side as it is for an equal change in the opposite side. (I.e. if we used x, y, width, height, then a "distance" calculation for a change to the left side would include both x and width, but an equal change in the right side would only include a change in width. Therefore these equal changes would have different "distances".)
