[Github-comments] [geany/geany] Size symbols and fold margins proportional to line height (#1738)

[Colomban Wendling]

> BTW why did you scale it off the line height not the character width?

Because Scintilla's filling the rectangle [margin width, line height] with the symbol, and most symbols we use are square, so it's the most efficient use of space.

> Also does SCI_TEXTHEIGHT() include the configurable extradescent/ascent or not?

Not sure, but my guess would be it's accounting for the whole height the line uses on screen.  But that's and interesting question.
