SDL will fail to construct an OpenGL 3.x/4.x context on Mac OS X,
unless ContextProfileFlags.CORE is specified.
Fixes issue #44
Upstream enhancement request at
https://bugzilla.libsdl.org/show_bug.cgi?id=2342
When running over remote desktop without hardware acceleration, there
are no GraphicsModes that support desktop composition. This patch adds
logic to avoid requesting composition-capable modes when running over
RDP.
Additionally, it changes the mode selection logic to consider modes that
support features partially (e.g. 16bpp color instead of 32bpp), albeit
with a heavy penalty over fully supported modes.
This patch adds a workaround for WM_STYLECHANGED messages that are not
delivered when running on Mono/Windows. If we detect Mono, then we call
HandleStyleChanged() directly in order to update the internal state of
our WinGLNative instance.
OpenTK now directly calculates the elapsed time between UpdateFrame
(RenderFrame) events and compares that directly to TargetUpdatePeriod
(TargetRenderPeriod). This significantly simplifies the implementation
and improves timing stability.
PlatformFactoryBase provides a common base interface for platform
backends. Platform backends should inherit from PlatformFactoryBase in
order to reduce code duplication.
LegacyJoystickDriver implements the legacy IJoystickDriver interface
(GameWindow.Joysticks) in terms of the new IJoystickDriver2 interface
(OpenTK.Input.Joystick).
This removes a large chunk of code from each platform backend, as they
no longer need to implement IJoystickDriver themselves. Additionally,
it adds support for device hot plugging which was previously missing.
This patch modifies GameWindow.Run() to use a single stopwatch instead
of two separate stopwatches for timing UpdateFrame and RenderFrame
events.
It improves timing accuracy for issue #20 (FrameEventArgs.Time
Inconsistencies)
DeviceAdded already checks that devices conform to the desired usage
pages. Checking again in DeviceRemoved is unnecessary - if a device
exists, then it has already passed muster.
JoystickAxis/Button.Last is used internally to allocate the correct
amount of storage for joystick axes and buttons. JoystickAxis.Axis10 is
required to support the maximum number of axes available on Mac OS X.
