* dispmanx: fix grabber issues with certain widths and support cropping The dispmanx grabber will produce garbage output if the destination pitch is not set to a multiple of 64 bytes (16 RGBA pixels). It can also fail when retrieving only a part of the image (eg in 3DSBS or TAB mode). Handle these cases by capturing the full image into a separate buffer with the pitch set to an appropriate value and manually handle 3D SBS/TAB left/top half copying. At this point supporting cropping like in the V4L2 grabber is rather easy and added as well. This'll help handling overscan setups (old TVs) and removing (possibly asymmetric) overscan borders. Cropping is disabled in video capture mode (when the DISPMANX_SNAPSHOT_FILL flag is set).

HYPERION
Hyperion is an opensource 'AmbiLight' implementation supported by many devices. The main features of Hyperion are:
- Low CPU load. For a led string of 50 leds the CPU usage will typically be below 1.5% on a non-overclocked Pi.
- Json interface which allows easy integration into scripts.
- A command line utility allows easy testing and configuration of the color transforms (Transformation settings are not preserved over a restart at the moment...).
- Priority channels are not coupled to a specific led data provider which means that a provider can post led data and leave without the need to maintain a connection to Hyperion. This is ideal for a remote application (like our Android app).
- HyperCon. A tool which helps generate a Hyperion configuration file.
- Kodi-checker which checks the playing status of Kodi and decides whether or not to capture the screen.
- Black border detector.
- A scriptable effect engine.
- Generic software architecture to support new devices and new algorithms easily.
