WinMM is optimized for general joystick use, not for the canonical
GamePad layout. Instead of exposing IGamePadDriver directly, it should
expose IJoystickDriver2 and use a mapping driver to get GamePad support.
Without this flag, OpenGL rendering does not work as expected.
Additionally, all WGL_ARB_pixel_format attributes are expected to be
specified in key-value pairs. Fixed double-buffering and stereoscoping
rendering attributes.
Fixed WGL_ARB_pixel_format attribute selection for doublebuffering,
stereoscopic rendering and hardware acceleration. Implemented
minimization strategy to select the optimal PixelFormatDescriptor in the
fallback path.
Instead of creating a list of all available formats and iterating
through that, we let the driver decide which is the best accelerated
format to use for the user parameters. If no such format exists, we fall
back to generic acceleration or software acceleration, in turn.
This affects issue #21
Don't filter window messages passed to our window (see
http://blogs.msdn.com/b/oldnewthing/archive/2005/02/09/369804.aspx).
Additionally, return the correct values for all messages we are actually
handling and clean up unmanaged memory after we are done with the
window.
Instead of combining PeekMessage+GetMessage, we can simply call
PeekMessage(Remove) to achieve the same effect. This also allows us to
remove the IsIdle property, which is no longer used anywhere.
The temporary context is now retained until the actual context has been
constructed. If we don't do this, then WGL_ARB_create_context may fail
to work correctly on specific GPUs (e.g. Intel). This may affect issue
#19.
The correct way to query number of available pixel formats is to use
Wgl.Arb.GetPixelFormatAttrib(NumberPixelFormatsArb), not
Wgl.Arb.ChoosePixelFormats. This fixes an issue where Intel drivers
would fail to report any pixel formats in GetModesARB, even when
WGL_ARB_pixel_format is supported.
It is now possible to indicate that an application is not DPI-aware. In
that case, OpenTK will let the operating system handle DPI scaling. This
results in worse visuals (pixel doubling) but allows non DPI-aware
applications to continue working.
WGL was autogenerated a few years ago but never touched after that.
Since we use a tiny fraction of all available methods, it makes sense to
remove the unused ones. This reduces dll size and improves startup
times.
On Windows, entry points for OpenGL 1.0 and 1.1 are not exposed by
wglGetProcAddress. We fall back to LoadLibrary+GetProcAddress when
wglProcAddress fails.
When we enter the modal resize loop on Windows with ClipCursor set, we
cause a feedback loop where every resize causes the cursor to move and
every move causes a new resize. To fix this, we need to ungrab the
cursor when we are enter the modal loop.
