Re: Font Rendering: Multiple FT_Faces and baselines

[takase1121]

Hi,

Thank you for pointing it out. I'm unsure about the strategy to align the 
baselines. The simplest would be aligning to the lowest / highest baselines, 
but that may break some faces. The other method would be the one I mentioned - 
calculate an "average" baseline and align to that, but it has the same 
drawbacks. Are there other methods that I've missed?
