font-angle

Arguments: font

Returns the angle of the specified font, which must be a font as created with make-font-ex, make-font, or ask-user-for-font. The value is an integer indicating degrees counterclockwise from the usual horizontal angle at which all strings that are drawn in the font will be drawn. The default is zero.

GTK note: On GTK, rotated text cannot be drawn. But if the angle is 90 or -90, then strings will be drawn vertically by stacking horizontal characters in a column. Otherwise strings will be horizontal as usual.
