Could dpi values for zoom be an acceptable replacement for
target-densityDpi?
Examples:
/* Set the zoom factor so that there is a 1-1 relationship between
physical and CSS pixels */
@viewport {
zoom: device-dpi
}
/* Set the zoom factor so that there are 160 CSS pixels per inch. */
@viewport {
zoom: 160dpi
}
You would lose the possibility to do something like this:
/* Set zoom factor so that a CSS pixel is rendered as 2x2 physical
pixels with a viewport width of 500px. */
@viewport {
target-densityDpi: device-dpi;
zoom: 2;
width: 500px;
}
Are there important use cases for combinations of target-densityDpi and
zoom?
