# A surface that is scaled relative to the root -- which is what APZ produces when it
# writes a pinch-zoom scale into a bound spatial node transform -- must propagate that
# scale to its child surfaces. The child here establishes its own raster root via a 3d
# transform, which puts it in a new coordinate system, so it takes its rasterization
# scale from the parent surface's world scale factors. If the parent reports a scale of
# one the child rasterizes at an eighth of the size it is drawn at, and its rounded-clip
# corners are stretched and lose their curve (bug 1899692).
