2 - see issue tracker, RoboVM specific issues are marked with [RoboVM]
3 - OGG is currently not supported by ObjectAL
6 - getVersion(), getJavaHeap(), getNativeHeap() not implemented
7 - getClipboard() not implemented properly, should at least support strings
9 - IOSApplicationConfiguration
10 - add compass, FBO bit depth, stencil bit depth
11 - add useGL2, requires implementation of GL10/GL11 for ios, and fixes in IOSGraphics
13 - newAudioDevice(), new AudioRecorder() not implemented
14 - OGG not supported, see if we can add that to ObjectAL
15 - IOSFileHandle, IOSFiles
16 - check if paths for internal, external, local are correct and working as intended
18 - need to store current device orientation for Input#getOrienation and consorts
19 - GLKView, is this supported from IOS 5+ onwards? i guess we can make that our minimum iOS version
20 - Add support for GL10/GL11
21 - Color format is fixed at RGB565, add RBGA8888 option in config
22 - make sure returned buffer format is correct if we expose setting color depth etc.
23 - setPreferredFramesPerSecond is hardcoded to 60, should make that configurable i guess
24 - check if density calculations are correct for ppi/ppc
25 - check if apps supporting both portrait and landscape work (resize, etc.)
26 - implement non-continuous rendering
28 - IOSInput#touchDown is a bit bonkers, with 64-bit iOS that might become an issue (it's an int, not a long)
29 - getAzimuth(), getPitch(), getRoll(), getRotationMatrix() need to be implemented and output the same as android
30 - see if we can programmatically show the keyboard and receive key events, if so map to gdx keycodes
31 - getPlaceholderTextInput() needs to be implemented
32 - vibrate(), cancelVibrate() needs to be implemented
33 - we should totally refactor setCatchBackKey and consorts eventually...
34 - add compass support, fix up isPeripheralAvailable(), including onscreen keyboard stuff
35 - getRotation() needs to be implemented
36 - getNativeOrientation() needs to be implemented, see IOSInput
40 - check if that actually works as intended
42 - add support for manipulating an already playing sound instance, seems to work through ALSource
43 - add support for pitch shifting, not sure ObjectAL can do that
