// We want to ensure that we're testing the non-Skia fallback version of
// DownscalingFilter, but there are two issues:
//  (1) We don't know whether Skia is currently enabled.
//  (2) If we force disable it, the disabled version will get linked into the
//      binary and will cause the tests in TestDownscalingFilter to fail.
// To avoid these problems, we ensure that MOZ_ENABLE_SKIA is defined when
// including DownscalingFilter.h, and we use the preprocessor to redefine the
// DownscalingFilter class to DownscalingFilterNoSkia.
