eglGetProcAddress cannot be used to retrieve
entry points of core functions. Instead, we
use [DllImport] for core functions and function
pointers for extension functions.

[Rewrite] Remove calli prototypes
When a function is called indirectly via a function pointer, its
prototype is not required (the prototype is added as a callsite at the
calli invocation.) Removing these prototypes reduces binary size by
roughly 400KB.

[Rewrite] Call DllImports directly
When a function does not have an allocated slot (i.e. slot = -1), then
we will call its DllImport signature directly.

[Bind] Do not allocate slots for DllImports

[Bind] Added option to use DllImports
This is necessary for the core functionality of OpenGL ES, where
eglGetProcAddress returns null or garbage (the latter on Android.)
This patch makes the following code work as expected:
```csharp
var gw = new GameWindow();
gw.TargetRenderFrequency = 60;
gw.Run();
```
Fixes issue #69
IGraphicsContext.VSync property is obsolete, but we have to call it in
the GraphicsContext.VSync implementation, so disable the obsolete
warning for this one use.
Wrap new generated binding calls with using ErrorHelper. Sets up a try
to call the method in and a finally block to call Dispose on the
ErrorHelper. Currently hardcoded to only work for the graphics modules.
GLHelper.cs contains a number of overloads that cannot be resolved by
VB.Net. We cannot remove them, as that will break
backward-compatibility, but we can hide them by moving them after the
autogenerated overloads in GL.cs.
Terrible hack, but it appears to work.
Issue originally reported at http://www.opentk.com/node/3554 as "OpenTK
1.1, VB.net and ambiguous functions."
Updated the Matrix4d CreateFromQuaternion methods to actually create
Matrix4d. They now mirror the Matrix4 CreateFromQuaternion methods,
just using doubles and the -d classes.
Previously, Matrix4d.CreateFromQuaterion actually created a Matrix4
from a single-precision Quaterion.
Using a bitfield does not save storage space in this case, and also
stops pattern matching from working (switch() statement in C# or match
… with expressions in F#.)
joyGetDevCaps() is an extremely slow call that allocates memory.
WinMMJoystick is now caching its results for a significant speedup in
Joystick.GetCapabilities() and GetState().
The cache is updated whenever a joystick device is removed. WIP to
handle device added notifications.
This protects against a potential denial-of-service issue during mode
selection, where the platform backend will try to reduce AA level until
a supported mode is found.
When refreshing the AvailableDevices list, it is important to set the
original resolution on any DisplayDevices that were previously available
to allow the RestoreResolution() method to work correctly.
Most OpenGL versions work with single-byte ASCII strings exclusively.
OpenGL 4.2 adds UTF8 encoded comments to GLSL shaders. Unfortunately,
UTF16 (.Net) to UTF8 conversions will usually modify the length of the
resulting byte array.
This is not currently possible to implement inside OpenTK, since the
binding generator does not know which length parameter corresponds to a
string parameter.
For this reason, and to maintain compatibility with older OpenGL
versions, we perform a destructive UTF16-to-ASCII encoding, which
replaces unsupported characters by '?'. This allows multi-byte post-4.2.
GLSL shaders to work as expected.
If non-destructive round-tripping of strings is required, the user will
have to use the IntPtr overload for string parameters and perform the
UTF16-to-UTF8 encoding/decoding manually. This need is very unlikely to
arise in practice.
