You keep to form this pet-peeve bikeshedding opinions and no amount of talking with technical reasons seems to phase you. Here's a short list of the times I conceded to such demands from you that I regret now. All made the spec worst:</div><div><br></div><div>- When I designed the ItemVariationStore, I wanted 32bit "variation index"es. You forced separate "major+minor" instead. This resulted in misunderstanding and faulty design in CFF2 (which Adobe also demanded not be reviewed by others formally). This also means everywhere in the spec now we need two fields instead of one, for no benefit whatsoever. It also leaks internal details of the ItemVarStore.</div><div><br></div><div>- Also in ItemVariationStore, I initially had it each region list its active axes. You forced your opinion of regions listing every axis in fvar even if inactive. I believe in "pay for what you use" design. With mine, adding a hundred axes wouldn't have made every ItemVariationStore consume more bytes. With yours it does. With mine, it would have magically enabled Higher-Order Interpolation. With yours it doesn't. Mine wasn't accidental, even though I had not thought about the HOI possibility. A good product will enable use-cases the original authors didn't think of. A bad product tries to enforce the limited worldview of the builder on the users for no good technical reason.</div><div><br></div><div>- You on behalf of MS demanded the `rvrn` feature be added, even though it was not needed. *Every* feature can get variations in what the committee designed. But MS / Office wanted a "fast path" because is stuck in mentality that "simple shaping" is a legitimate design and should be supported by the font format. Because of that decision, and because of another bad decision unilaterally forced by MS: that lookups are NOT applied solely by lookup-number like the spec says, now `rvrn` is useless and confusing because some designs are made easier if variation substitutions are applied first, other designs are made easier if variation substitutions are applied last.</div><div><br></div><div>- You on behalf of MS demanded that LSB/RSB variations (and by extension TSB/BSB variations) be encoded in the HVAR/VVAR tables because the obsolete GDI "ABC" API "needs them" and can't be bothered to get them from the outlines. Everyone else didn't want that. It was later pointed out by Dave Lemon that the side-bearing variations of OT1.8 varfonts CANNOT be represented in OT1.8 variation model. So the spec is faulty now. I fought and got MS/you to agree to make those variations at least optional.</div><div><br></div><div>- MS, including you, blocked from progression any of the OTlayout proposals that me and Martin Hosken prepared, that were a path to truly advancing OTlayout towards being able to handle Nastaliq.</div><div><br></div><div>- As a sub-example of the above, Martin and I wrote the "glyph filtering" proposal:</div><div><br></div><div> <a href="https://github.com/OpenType/opentype-layout/blob/master/proposals/glyph_filtering.md">https://github.com/OpenType/opentype-layout/blob/master/proposals/glyph_filtering.md</a></div><div><br></div><div>to address a very real need from designers. You/MS blocked that with the faulty "security issue" of allowing jumping over arbitrary number of glyphs. It didn't convince you that it was already possible to jump over arbitrary number of glyphs if the font declares all glyphs (or any!) as GDEF class mark. Indeed, Andrew Glass & John Hudson's Soyombo font *depends* on that.</div><div><br></div><div>That's just a few I could type right now. There's probably another dozen I will type next week.</div><div><br></div><div>It is the fact that you don't see any of these as problematic that I question your fairness and objectivity.</div><div><br></div><div>To everyone who tells me to drop the past and focus on the future, I won't as long as Peter and/or MS don't change their stance. That would be continuing with the status quo and I will refuse to do that. Albert Einstein : “Insanity is doing the same thing over and over again and expecting different results.” </div><div><br></div><div>Want me to drop all my grudges? You and/or MS admit past faults (no "but"s), offer a sincere apology, and commit to not repeat them moving forward.</div><div><br></div><div>behdad</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div lang="EN-US"><div class="gmail-m_-7368203435300679871WordSection1"><p class="MsoNormal"> </p><p class="MsoNormal"><u></u></p>

the similarly-named types in computers and languages, because the OpenType ones are always big-endian. If he had consulted others, we could have reached a universally-unambiguous and clear names.<u></u><u></u></p>
