However, `-moz-outline-radius` should still override any `border-radius`.
This is primarily done for backward compatibility with some themes.
Additionally, it also allows for more advanced outline control than the CSS spec provides, without breaking spec.
Finally, if the spec is ever updated to include `outline-radius`, we'll be ready to drop the `-moz-` prefix!
Note: BZ 315209 has an inadvertent double-negative in nsDisplayList.cpp:
HasRadius() essentially returns the opposite value it should.
Only blur one quadrant of a box-shadow and mirror it to the other quadrants.
This applies only if the corners are symmetrical (square corners or equal
corner radii) otherwise we'll fall back to the old method.

Aspect Ratio handling simplified by using floating point integers:
- Multiplication of value (or inverse value) to a known side for Scaling
- No unequal equal values such as "4/3" vs "8/6" vs "20/15"
- Truly "Empty" aspect ratios, even if one dimension is not 0
Before issue #146, border-radius on row groups, rows, column groups, or columns don't apply to the background of each cell, yet the border-radius on the cell itself does.
After issue #146, the behaviors changed. In this patch, I tried to revert the behaviors of border-radius on table row groups, rows, column groups, or columns back to what happened before issue #146.
Also: Don't override GetBorderRadii in nsBCTableCellFrame.
This causes transparent stops to behave like "true transparent" instead
of "transparent black", even in RGBA space.
i.e.: the gradient will transition to a transparent version of the color
adjacent to the transparent color stop (on either side if not on the edge).
