    application sources or binaries.

  - it's relatively simple to produce a new "target mode" if a new
    incredibly smart new hinting technique comes in, or when we'd like
    to support optimisations specific to other kinds of displays (TVs for
    example, can benefit from a hinting scheme where you _avoid_ aligning
    stems to the pixel grid, in order to reduce flickering effects).

SVG model defines some high level rendering and hinting flags <> which would be useful in freetype. E.g. to render smoothly animated text, application will use geometricPrecision mode.
