[HarfBuzz] Alternate/random glyphs

[Jonathan Kew]

If the font you're talking about is 
https://www.myfonts.com/fonts/pintassilgo/daft-brush?tab=techSpecs, then 
it does claim to include a 'rand' feature.

I don't know how InDesign attempts to use 'rand' (if at all), but given 
the description of the feature in 
https://docs.microsoft.com/en-gb/typography/opentype/spec/features_pt#tag-rand, 
which says:

 > "For GIDs found in the rand coverage table, the application passes a 
GID to the rand table and gets back one or more new GIDs. The 
application selects one of these either by a pseudo-random algorithm, or 
by noting the sequence of IDs returned, storing that sequence, and 
stepping through that set as the corresponding character code is invoked."

there is no expectation that it will produce consistent results from one 
application to another, or one document to another (or even in repeated 
rendering of the same document).
