I can’t seem to change image resampling quality on OSX.
First off, CoreGraphicsContext::setInterpolationQuality doesn’t even use all of the available enum values.
Second, toggling it has no effect on resized drawImage(). This can be seen in the Graphics::2D Rendering::Images demo (animate size to see resampling better). The resampling quality seems to be really low regardless of setting.
I would appreciate if someone from the Juce team could look into this.
