+# the vaio-p display can do upscaling with bilinear filtering, which saves our
+# poor intel atom cpu from having to upscale an image to a very pixel-dense
+# screen in software. thankfully, the density can also work to our advantage
+# here; it means the monitor's upscaling doesn't look too bad at lower
+# resolutions! since we have no GPU driver, we want to take advantage of this
+# as much as possible by full-screening applications and using appropriate
+# integer-multiple resolutions.
