[bug] TT hinting bug in latest cutting-edge build (1313)

HI all, I’ve just upgraded from build 1312 (Mar 30) to 1313 (Apr 9) and it seems that the TT hinting instructions aren’t being interpreted correctly, leading to heavily distorted glyphs that were hinted using the Interpolation instruction. This applies both in the preview and also in the TT files after export. Switching back to 1312 solves this problem.
