Glutin Version v0.29.1

• Fix build failures when building from crates.io

Glutin Version v0.29.0

• Fix crash when creating OpenGLES context without explicit version.
• Add buffer_age method on WindowedContext.
• Return an Err instead of panicking when surfaceless GLX context creation fails on Linux.
• Fix compilation on Android:
  • Switch from StaticStructGenerator to StructGenerator to dynamically load symbols.
  • Replace android_glue dependency with raw-window-handle, and remove broken lifecycle event handling.
  • Glutin can now be used on Android, however, the application must ensure it only creates the Context following a winit Event::Resumed event, and destroys the Context in response to a Event::Suspended event.
• Updated winit dependency to 0.27.0. See winit's CHANGELOG for more info.
• On Windows, build_raw_context now uses isize for hwnd to follow winit change.

Glutin Version v0.28.0

• On Windows, fixed a panic for headless contexts because of active drag-and-drop (OleInitialize failed! Result was: RPC_E_CHANGED_MODE)
• Updated winit dependency to 0.26.0. See winit's CHANGELOG for more info.

v0.27.0

• Updated winit dependency to 0.25.0. See winit's CHANGELOG for more info.

Glutin Version 0.26.0

• Updated winit dependency to 0.24.0. See winit's CHANGELOG for more info.

Glutin Version 0.25.1

• X11 and Wayland are now optional features (enabled by default)

v0.25.0

• Updated winit dependency to 0.23.0. See winit's CHANGELOG for more info.
• Avoid loading libEGL.dll from PATH on Windows.

v0.21.0

• Added treat_as_current function.
• Breaking: Replaced CreationErrorPair enum variant with CreationErrors.
• Added Clone to ContextBuilder.
• Added headless example.
• Removed internal code relating to libcaca.
• Implemented Debug on all public facing types.
• Dropping contexts on platforms using egl and/or glx no longer resets the
  current context, if the context dropped wasn't the current context.
• Added context sharing support to MacOS.
• Breaking: Removed ContextTrait.
• Breaking: Renamed OsMesaContextExt to HeadlessContextExt. Added functions
  for using egl-surfaceless.
• Breaking: Changed WindowedContext and RawContext into typedefs of
  ContextWrapper.
• Breaking: Removed new_windowed and new_headless from WindowedContext
  and Context, respectively.
• Breaking: Added two new types, NotCurrent and PossiblyCurrent,
  which RawContext, WindowedContext, ContextBuilder and Context are now
  generic over.
• Added {make,treat_as}_not_current function to {Raw,Windowed,}Context.
• We now load libGL.so instead of libGLX.so.
• Fixed bug where we drop the hidden window belonging to a headless context on
  on X11 and/or Wayland before the actual context.
• "Fixed" bug where we will close EGLDisplays while they are still in use by
  others. Angry and/or salty rant can be found in glutin/src/api/egl/mod.rs,
  you can't miss it.
• Breaking: WindowedContexts now deref to Context, not Window.
  Please use .window() to access the window.

v0.20.0

• We no longer load libEGL.so and libGL.so multiple times.
• Fixes Context::is_current incorrectly returning false.
• Made ContextBuilder's pf_reqs public.
• Breaking: Renamed GlContext{,Ext} to ContextTrait{,Ext}.
• Breaking: Renamed GlWindow to WindowedContext.
• Implemented context sharing support for Windows and Linux.
• Added support for contexts made from raw parts for Windows and Linux.
• Breaking: Removed shareable_with_windowed_contexts. Now you must build
  OsMesa contexts via a separate extension.
• Added ContextBuilder::build_{windowed,headless} methods.
• Breaking: Renamed Context::new to Context::new_headless. new_headless now accepts dimensions for the off-screen surface backing it.
• Breaking: Renamed GlWindow::new to WindowedContext::new_windowed.
• On X11 and Wayland, you can now use shared contexts, however, one limitation
  of the Wayland backend is that all shared contexts must use the same events
  pool as each other.
• Added context sharing support to windows.
• Improved docs.
• Refactored code to be more consistent/cleaner. Ran rustfmt on everything.
• Added NetBSD support.
• Breaking: Removed new_shared function from Context and GlWindow, in favor of new.
• Added build method to ContextBuilder.
• Added get_egl_display method to GlContextExt trait and its implementation for platforms.
• Removed minimum supported Rust version guarantee.
• NoBackendAvailable is now Sync, as a result CreationError is also Sync.
• Update winit dependency to 0.19.0. See winit's CHANGELOG for more info.

v0.19.0

• Breaking: The entire API for headless contexts has been removed. Please instead use Context::new() when trying to make a context without a visible window. Also removed headless feature.
• Breaking: Types implementing the GlContext trait must now be sized.
• Breaking: Added new CreationErrorPair enum variant to enum CreationError.
• Remove requirement for EGL dev packages on Wayland.
• Update winit dependency to 0.18.0. See winit's CHANGELOG for more info.
