| <meta name="assert" content="The background here extends to the whole |
| canvas, and a transform on the root element must transform the whole |
| canvas, background included. Thus the entire tiled background of |
| left-pointing triangles needs to be rotated 180 degrees (same as scale(-1)) |
| around the top center of the viewport, which is the default |
| transform-origin of 50% 50% in this case. An implementation that doesn't |
| draw the background on parts of the canvas outside the viewport might |
| incorrectly display nothing, because the part of the background that's |
| supposed to be rotated into view was initially above the visible part of |
| the canvas."> |
