* Return a Pageimage object sized/cropped to the specified dimensions.

* to override. These include: 'quality', 'upscaling', and 'cropping'. When a string, it is assumed you are specifying
* a cropping value. When an integer, it is assumed you are specifying a quality value. When a boolean, it is assumed you
* are specifying an 'upscaling' toggle on/off.
*
* Cropping may be specified either in the options array with the 'cropping' index, or via a 3rd string param to the function.
* Possible values for 'cropping' include: northwest, north, northeast, west, center, east, southwest, south, southeast.
* If you prefer, you can specify shorter versions like 'nw' for 'northwest', or 's' for 'south', etc.
* If cropping is not specified, then 'center' is assumed.
* To completely disable cropping, specify a blank string.
*
* Quality may be specified either in the options array with the 'quality' index, or via a 3rd integer param to the function.
* Possible values for 'quality' are 1 to 100. Default is 90. Important: See the PLEASE NOTE section below.
*
* Upscaling may be specified either in the options array with the 'upscaling' index, or via a 3rd boolean param to the function.
* Possible values for 'upscaling' are TRUE and FALSE. Default is TRUE. Important: See the PLEASE NOTE section below.
*
* PLEASE NOTE: ProcessWire doesn't keep separate copies of images with different 'quality' or 'upscaling' values. If you change
* these and a variation image at the existing dimensions already exists, then you'll still get the old version.
* To clear out an old version of an image, use the removeVariations() method in this class before calling size() with new
* quality or upscaling settings.
