Ebrahim Byagowi 759df46575 [style] Hide behind HB_EXPERIMENTAL_API compile flag 2020-06-04 20:33:39 +04:30
Ebrahim Byagowi de0ec5f4fe [style] give ptem value when asked for opsz
ptem, used for AAT's tracking/`trak` table is equivalent to opsz of variable fonts.

For variable AAT fonts, such as SFNS, ideally variable axis of the hb_font_t
should be set and equivalent to ptem, https://crbug.com/1005969#c37

Ebrahim Byagowi 22037499b4 [style] New experimental API, hb_style_get_value
Searches variation axes of a hb_font_t object for a specific axis first,
if not set, then tries to get default style values from different
tables of the font.
