/** Config: JUCE_ENABLE_DIRECT2D_CLEARTYPE_FONT_SMOOTHING
Setting this flag will *enable* Windows ClearType subpixel font antialiasing when using
the Direct2D renderer, if preferred by the end user. This is off by default due to
issues with transparency, certain compositions and transformations so make sure the
output looks acceptable for your use cases.
