[filter-effects] hue-rotate() is not accurate for saturated colors

[AlexApps99]

The current definition of hue-rotate() is based on an SVG filter, which uses a matrix transformation on RGB color to calculate the resultant color.

This is not very desirable for some usecases, for example, a general CSS userstyle to make pages appear like a "dark mode" with invert(100%) hue-rotate(180deg) on the entire document, then selectively hue-rotate(-180deg) invert(100%) to elements such as images and videos.

I would expect a style like this to undo the effects of the inversion, so the colors of the elements are normally colored.
The actual effect is slightly off-color, due to the limitations of the current method of hue-rotate().

While it is extremely unlikely the current definition can be changed, it would be great if a new effect could be added that behaved as expected.
