Impossible to use different flavours of a font in the same project without changing the font's "Font Family"

    Description

      We use the default Android font in our embedded application:
      http://developer.android.com/design/style/typography.html

      We want to use different flavours of this font (Regular, Light, Bold, Medium) in our app.

      However, from QML, the font can only be specified by "font.family". All of these .ttf files contain the same font family name (which makes sense).

      Setting font.bold to true on the Roboto Regular font produces a different end result than using the Roboto-bold.ttf file.
      Likewise, playing around with font.weight does not yield any decent result. Both of these seem to process the existing font instead of looking for the different flavors of the font (like native applications do).

      We need a way of accessing the different flavours of a font from QML.

      For now, we have worked around this issue by editing the Roboto font and changing the "Family name" field and saving them as totally different fonts.
