First, It is a test harness for screen savers. When it launches, it
looks around for .saver bundles (in the current directory, and then in
Second, it can be used to transform any screen saver into a standalone
program. Just put one (and only one) .saver bundle into the app
- bundle's Contents/PlugIns/ directory, and it will load and run that
+ bundle's Contents/Resources/ directory, and it will load and run that
saver at start-up (without the saver-selection menu or other chrome).
This is how the "Phosphor.app" and "Apple2.app" programs work.
+
+ Third, it is the scaffolding which turns a set of screen savers into
+ a single iPhone / iPad program. In that case, all of the savers are
+ linked in to this executable, since iOS does not allow dynamic loading
+ of bundles that have executable code in them. Bleh.

+ According to a StackOverflow comment:
+
+ The iPhone 6+ renders internally using @3x assets at a virtual
+ resolution of 2208x1242 (with 736x414 points), then samples that down
+ for display. The same as using a scaled resolution on a Retina MacBook
+ -- it lets them hit an integral multiple for pixel assets while still
+ having e.g. 12pt text look the same size on the screen.
+
+ The 6, the 5s, the 5, the 4s and the 4 are all 326 pixels per inch,
+ and use @2x assets to stick to the approximately 160 points per inch
+ of all previous devices.
+
+ The 6+ is 401 pixels per inch. So it'd hypothetically need roughly
+ @2.46x assets. Instead Apple uses @3x assets and scales the complete
+ output down to about 84% of its natural size.
+
+ In practice Apple has decided to go with more like 87%, turning the
+ 1080 into 1242. No doubt that was to find something as close as
+ possible to 84% that still produced integral sizes in both directions
+ -- 1242/1080 = 2208/1920 exactly, whereas if you'd turned the 1080
+ into, say, 1286, you'd somehow need to render 2286.22 pixels
+ vertically to scale well.
