tweak not caching images in Skia drawing when upscaling (tdf#132438)
The change done for tdf#134237 was meant to avoid caching of very
large images when zooming in. But it turns out that it happens
quite often that we get asked to draw something larger than
the drawing area, such as when scrolling a document with a larger
image. So tweak the check to hopefully avoid only huge images
or when upscaling a lot.
