I think ImageBufferOptions can be moved to the end just before CreationContext and it can have a default value { }. So many callers do not have to pass { } for it.

Should this be moved to ImageBuffer.h since it is only used for ImageBuffer?

This code is repeated many times in the patch. Can't we add an inline function in RenderingMode.h

inline OptionSet<ImageBufferOptions> bufferOptions(RenderingMode renderringMode)
{

}

Or something else. And use this inline directly in the call to ImageBuffer::create(tileRect.size(), bufferOptions(filter.renderingMode()), ...).

There’s a "RendingMode" typo in here.

I suggest grepping for "endingMode".
