[css-fonts] It should be possible to slant glyphs to the left for italics/oblique #8914
Description
Some right-to-left writing systems italicise by sloping the letters to the left (ie. in the reading direction).
Here is an example from the N'Ko Kigelia font. The creators of the Kigelia font conducted research with the users and standardisation body for the N'Ko script what their preference was, and this was the user's preference for the default styling of N'Ko italics.
Some Hebrew authors also prefer to slope in the direction of reading, although this tends to be author preference.
The following is a photo of an Arabic newspaper letterhead. See the oblique text in the middle line.
The CSS font-synthesis properties don't provide any mechanism to indicate the direction of lean. Could we please add something to support these international users.
