+// We used to have mode_squash_5x here as well, but it got removed.
+// 5x squashing gives 1280x1000, which is very close to the 4x stretched
+// 1280x960. The difference is that 1280x1000 is the wrong aspect ratio.
+// It was ultimately decided that it was better to use the right aspect
+// ratio and have slightly larger borders than to have slightly smaller
+// windowboxing borders. It also means that the aspect ratio is correct
+// when running at 1280x1024. See bug #460 for more details, or this
