Special case for double letters

[pentamassiv]

Some words that contain double letters look odd due to the texture healing. One example is the word "Humming". The two letters 'm' have a different width and one of them looks squished. Maybe do not do texture healing if it is a double letter?

You can see what I mean here:

Some other odd-looking cases I've encountered:
immediate
0x00FFFF00

This is definitely a matter of personal preference. If it gets added, it should be toggleable.

Some might even want this exception to apply if the repeated characters aren't right next to each other; see #90. The ideal situation would be to make it so that if any two instances of the same character are within a certain user-configurable distance of each other (and on the same line), they must be drawn exactly the same. Or you could make it a bit looser, such that two nearby instances may mix and match their narrow and medium variants ("contextual alternates"), or their medium and wide variants, but not their narrow and wide variants.

And then you could go even further by adding this same distance requirement vertically.

These do, however, add increasing levels of complexity to the internal logic that decides which variant to use for each instance of each character.

i am physically unable to contribute right now, but i would like to share how double-letter cases could be handled:

• you have a word like “humming”. the first m is normal, but the second one is wider.
• you introduce a ligature, whose width would be the sum of the width of the first m and the second m.
• in that ligature, those ms are distributed fairly.

in total, for a pair of two repeating letters, you will need only 2 new ligatures… per every single character you have:

1. special on left, normal on right (like in the word immediate);
2. normal on left, special on right (like in your example, the word humming).

“special” refers to the texture-healed glyph width: special i is the one which gives space, special m is the one which takes space.
