font/sfnt: fix hmtx table size validation The library assumes the hmtx size to be equal to 2*nGlyph + 2*nHm, which is a simplification of 4*nHm + 2*(nGlyph-nHm) as described in the spec. However, fonts seen in the wild sometimes omit the second term (left side bearings), making validation to fail. CL fixes the validation code by allowing to omit the second term. Fixes golang/go#28379 Change-Id: I2293e498e72f95e5fe08c2b375ea7b020d06cde3 Reviewed-on: https://go-review.googlesource.com/c/144080 Reviewed-by: Nigel Tao <nigeltao@golang.org>
