Some fonts support multiple scripts, for example, some fonts for Korean supports not only "Kore" but also "Jamo". To select fonts based on their multiple languages, this CL introduces the following changes: - Compares all languages of the font family and use the maximum score for font selection. - Even if each language of the font family doesn't support the requested language, the font get score of 2 if the requested font is covered by all of the languages of the font family. For example, the font for "ko-Hang,ko-Hani" gets score of 2 for the requested language "ko-Kore". Bug: 26687969 Change-Id: I7f13b51464c9b01982bb573251d77052b9ddbd70
