The 4.5 spec moves BLEND_ADVANCED_COHERENT_KHR from
KHR_blend_equation_advanced to KHR_blend_equation_advanced_coherent.
Add a deprecated token to maintain binary compatibility.
As a convenience, int overloads are provided for IntPtr size
parameters (corresponding to BufferSize or size_t). In the vast
majority of cases, a 32bit int is sufficient for buffer sizes,
so these overloads avoid the necessity of annoying (IntPtr) casts.
If more than 2^31-1 elements are required, the IntPtr overloads
remain available. (As always, this requires a 64bit runtime
environment.)
These valuators are not available on all systems. We now check
explicitly for support, instead of returning invalid results.
Additionally, unknown valuator names are now printed to the
debug log.
It appears that Mono 3.4.0 fails to marshal SDL_JoystickGUID
correctly when used as a return value. Changing the fixed buffer
to a couple of long fields allows the struct to be marshalled
correctly.
On SDL, DPad inputs were not correctly translated from joystick
hat inputs.
Updated MappedGamePadDriver so that it will correctly recognize
combined joystick hat directions e.g. DPadLeft should be true when
DownLeft, Left, or UpLeft are returned from the joystick hat.
The stored delegate list would store delegates indefinitely, causing a
memory leak. It is now the responsibility of each class to maintain
references to any callback functions it defines.
Devices are now explicitly closed when they a DeviceRemoved event is
received. Additionally, exceptions are no longer allowed to escape into
unmanaged code, where they might crash the runtime.
Callbacks are now explicitly marked as unmanaged pointers with the
correct (platform-defined) calling convention. Exceptions raised inside
these callbacks are no longer allowed to escape into unmanaged code,
where they will crash the runtime.
Additionally, the window is now only closed on the UI thread, and only
if it is actually open.
CocoaNativeWindow now checks for and reports failures to allocate
resources in its constructor. Additionally, it no longer calls UI
methods in the finalizer thread, as those methods will crash on Cocoa.
There are static methods that rely on `OpenTK.Platform.Factory` having
a static constructor. We need to fix those first, before we can remove
this constructor.
