//| :mod:`displayio` --- Native display driving
//| =========================================================================
//|
//| .. module:: displayio
//|   :synopsis: Native helpers for driving displays
//|   :platform: SAMD21, SAMD51, nRF52
//|
//| The `displayio` module contains classes to manage display output
//| including synchronizing with refresh rates and partial updating.
//|
//| Libraries
//|
//| .. toctree::
//|     :maxdepth: 3
//|
//|     Bitmap
//|     BuiltinFont
//|     ColorConverter
//|     Display
//|     FourWire
//|     Glyph
//|     Group
//|     OnDiskBitmap
//|     Palette
//|     ParallelBus
//|     Shape
//|     TileGrid
//|
//| All libraries change hardware state but are never deinit
//|


//| .. method:: release_displays()
//|
//|   Releases any actively used displays so their busses and pins can be used again. This will also
//|   release the builtin display on boards that have one. You will need to reinitialize it yourself
//|   afterwards.
