Note that the Wikipedia page you cite says that the use of "resolution" to refer to pixel dimensions is a misnomer, though a common one, and states that in other contexts it refers to the pixel density. "Resolution" can also be stated as a flat number of pixels in some contexts, such as digital camera resolutions. It's just an overloaded term that can refer to a couple of closely-related concepts. When used on images, "resolution" generally refers to the pixel density. I think the usage of "resolution" to refer to pixel density is sufficiently common to be understandable, and the other uses of resolution are either already achievable via other MQs (such as 'width' and 'height'), or aren't really meaningful. ~TJ
