Behdad Esfahbod 1b7994cb3a [aat] Support feature ranges
The hard way...

A bit uglier than I liked it to be, but is proper at least.

Garret Rieger 0f01a83622 [subset] add basic test for CFF2 subsetting.
FontTools does not yet support CFF2 subsetting so we can't add a comparison test. Instead add a golden file test.

Behdad Esfahbod 24a4d397ba [aat] Allow disable feature ranges
Fixes https://github.com/harfbuzz/harfbuzz/issues/4020

This is a hack.

To implement this properly we need to treat runs with different features
as independent runs for running the state machine, as the subtable flags
might be different. That would be a significant change to our internal
implementation.

Matthias Clasen a085efa699 test-paint: Fix font setup for ft
We must call hb_ft_font_set_funcs after
setting the font scale.

Matthias Clasen 26f713a7f5 paint-test: Use larger scales
A scale of 20 is noise, so use 1000.
2023-01-09 12:54:06 -05:00
Behdad Esfahbod e886b6b8a6 [test-draw] Use a larger scale
A scale of 20 is in the noise category for us. Using a larger
scale makes the test pass.

Matthias Clasen f3ce137420 test-paint: Be more flexible for expected results
When generating the expected output with GENERATE_DATA=1,
Glib's test framework puts out some comments at the top
of the file. Ignore them when comparing the expected
output. This makes it possible to directly use the output
of

GENERATE_DATA=1 ./test-paint -p TESTCASE

as expected result for TESTCASE.
