Quite a few things going on in this commit: - Enable bitmap strikes by default in Paint objects. The SkPaint parameter that enables bitmap strikes was not previously included in DEFAULT_PAINT_FLAGS. This effectively disabled bitmap fonts. Oops! It's for the best, though, as additional work was needed in Skia to make bitmap fonts work anyway. - Complain if TEXTURE_BORDER_SIZE is not 1. Our glyph cache code does not currently handle any value other than 1 here, including zero. I've added a little C preprocessor check to prevent future engineers (including especially future-me) from thinking that they can change this value without updating the related code. - Add GL_RGBA support to hwui's FontRenderer and friends This also happened to involve some refactoring for convenience and cleanliness.
