*
|
|
* In general, the values are converted from page-relative device pixels to viewport-relative app units,

* and then back to page-relative device pixels (now as ints). The first half of this is only slightly
|
|
* lossy, but it's enough to throw off the numbers a little. Because of this, when gecko calls
|
|
* ScaleToOutsidePixels to generate the final rect, the rect may get expanded more than it should,

* ending up a pixel larger than it started off. This is undesirable in general, but specifically
|
|
* bad for tiling, because it means we means we end up painting one line of pixels from a tile,
|
|
* causing an otherwise unnecessary upload of the whole tile.
|
|
*
|
|
* In order to counteract the rounding error, this code simulates the conversions that will happen

* to the display port, and calculates whether or not that final ScaleToOutsidePixels is actually
|
|
* expanding the rect more than it should. If so, it determines how much rounding error was introduced
|
|
* up until that point, and adjusts the original values to compensate for that rounding error.
