Calculate coordinates in an image, assuming the image has been scaled from (oH x oW) pixels to (nH x nW) pixels

Parameters:

x - X position (pixels) to translate

y - Y position (pixels) to translate

origImageW - Original image width (pixels)

origImageH - Original image height (pixels)

newImageW - New image width (pixels)

newImageH - New image height (pixels)

Returns:

New X and Y coordinates (pixels, in new image)
