test-document with Andale Mono that doesn't provide Italic/Oblique styles	none

Description hdu@apache.org 2014-01-27 13:50:33 UTC

A couple of fonts don't provide italic typefaces themselves. Slanting their regular version doesn't provide it either but it gives an approximation and it allows to distinguish texts that only differ in their "italic" attribute.

Comment 1 hdu@apache.org 2014-01-27 14:03:21 UTC

On our Unix platforms we have been using the matrix (1, 3/8, 0, 1) for over a decade now for the italic-emulation, so we should do something similar for our CoreText based platforms.
