Hi,
In memory optimized `tt_sbit_decoder_load_image', when index_format is 2
or 5, image_offset is added to image_start twice.
This bug is trivial. But as I don't have a font to test, I send this
patch to the list for review, in case I misunderstood the code.
BTW, are there fonts having EBSC table? It seems fun to add support
for this table.
