* INTERPLUGIN MESSAGING
***************************************************************************/
/*
* Plugin messages are defined as 32-bit integers. Messages below 0x00FFFFFF
* are reserved for X-Plane and the plugin SDK.
*
* Messages come with a pointer parameter; the meaning of this pointer depends
* on the message itself. In some messages, the pointer parameter contains an
* actual typed pointer to data that can be inspected in the plugin; in these
* cases the documentation will state that the parameter "points to"
* information.
*
* in other cases, the value of the pointer is actually an integral number
* stuffed into the pointer's storage. In these second cases, the pointer
* parameter needs to be cast, not dereferenced. In these caess, the
* documentation will state that the parameter "contains" a value, which will
* always be an integral type.
*
* Some messages don't use the pointer parameter - in this case your plugin
* should ignore it.
*
* Messages have two conceptual uses: notifications and commands. Commands
* are sent from one plugin to another to induce behavior; notifications are
* sent from one plugin to all others for informational purposes. It is
* important that commands and notifications not have the same values because
* this could cause a notification sent by one plugin to accidentally induce a
* command in another.
*
* By convention, plugin-defined notifications should have the high bit set
* (e.g. be greater or equal to unsigned 0x8000000) while commands should have
* this bit be cleared.
*
* The following messages are sent to your plugin by X-Plane.

/***************************************************************************
* Plugin Features API
***************************************************************************/
/*
* The plugin features API allows your plugin to "sign up" for additional
* capabilities and plugin system features that are normally disabled for
* backward compatibility. This allows advanced plugins to "opt-in" to new
* behavior.
*
* Each feature is defined by a permanent string name. The feature string
* names will vary with the particular installation of X-Plane, so plugins
* should not expect a feature to be guaranteed present.
*
* XPLM_WANTS_REFLECTIONS
* ----------------------
*
* Available in the SDK 2.0 and later for X-Plane 9, enabling this capability
* causes your plugin to receive drawing hook callbacks when X-Plane builds
* its off-screen reflection and shadow rendering passes. Plugins should
* enable this and examine the dataref sim/graphics/view/plane_render_type to
* determine whether the drawing callback is for a reflection, shadow
* calculation, or the main screen. Rendering can be simlified or omitted for
* reflections, and non-solid drawing should be skipped for shadow
* calculations.
*
* **Note**: direct drawing via draw callbacks is not recommended; use the
* XPLMInstance API to create object models instead.
*
* XPLM_USE_NATIVE_PATHS
* ---------------------
*
* available in the SDK 2.1 and later for X-Plane 10, this modifies the plugin
* system to use Unix-style paths on all operating systems. With this enabled:
*
* * OS X paths will match the native OS X Unix.
* * Windows will use forward slashes but preserve C:\ or another drive letter
* when using complete file paths.
* * Linux uses its native file system path scheme.
*
* Without this enabled:
*
* * OS X will use CFM file paths separated by a colon.
* * Windows will use back-slashes and conventional DOS paths.
* * Linux uses its native file system path scheme.
*
* All plugins should enable this feature on OS X to access the native file
* system.
*
* XPLM_USE_NATIVE_WIDGET_WINDOWS
* ------------------------------
*
* Available in the SDK 3.0.2 SDK, this capability tells the widgets library
* to use new, modern X-Plane backed XPLMDisplay windows to anchor all widget
* trees. Without it, widgets will always use legacy windows.
*
* Plugins should enable this to allow their widget hierarchies to respond to
* the user's UI size settings and to map widget-based windwos to a VR HMD.
*
* Before enabling this, make sure any custom widget code in your plugin is
* prepared to cope with the UI coordinate system not being th same as the
* OpenGL window coordinate system.
