Non-accelerated contexts are now considered iff no accelerated contexts
are available. Additionally, a GraphicsException will be thrown if
context construction fails for any reason, instead of causing a runtime
crash.
External mice will now report horizontal scrolling in the low-level
`Mouse.GetState()` API. The touchpad apparently creates an emulated
mouse device that does not report horizontal wheel scrolling events.
Touchpad support probably requires a proper multitouch implementation.
NativeWindowBase will now clear all keyboard keys when losing focus.
This prevents keys from getting stuck when refocusing the window.
[Win] Also fixed WindowState.Maximized when WindowBorder is Hidden and
the window is minimized.
On HiDPI displays, the client rectangle is using a pixel-based
coordinate system, while the screen is using a point-based coordinate
system. PointToClient/PointToScreen now correctly accounts for that.
- The complete mouse state is now available in mouse events
- Horizontal wheels are now supported
- MouseState now takes up less memory and has a simpler internal
implementation.
All INativeWindow implementations are now derived from
NativeWindowBase. They no longer implement legacy IInputDriver
themselves, but rather rely on LegacyInputDriver provided by
NativeWindowBase for compatibility. They also implement the new Mouse*
events.
Cocoa sets the desktop origin at the bottom-left of the main screen,
with +y going up. OpenTK is setting the origin at the top-left of the
main screen, so we need to invert the y-axis.
EGL and NSOpenGL do not offer an EXT_swap_control_tear equivalent so
use regular vsync for now. The relevant extension string is now
correctly checked on WGL and GLX.
NewEventHandlerUPP fails to load when running through MonoKickstart. It
appears that this function is only used for old PPC systems that had
trouble with function pointers - sample code online indicates that we
do not need to call this.
To create a context for the GTK GLWidget, you need to be able to
specify the exact NSView you want the OpenGL context to apply to. Also,
you don’t want to initialise the NSApplication in this situation, which
the CocoaContext did before (unintentionally).
