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.)
GameWindowStates will now display the average fps and draw three moving
boxes based on different timing methods.
If the timing implementation in OpenTK is working correctly, all three
boxes should be moving at the same speed.
This test uses SDL2 to create a window and an OpenGL context. It then
uses OpenTK to render into the external SDL2 context. If everything is
working correctly, a black window should appear and gradually turn
white before disappearing.
By mistake, this code would always create a desktop context. The correct
approach is to create an embedded (EGL) context and only fallback to
desktop if that doesn't work.
EnableCap.ColorArray is part of the client state and must be enabled
with GL.EnableClientState, not GL.Enalbe. This is a potential fix for
http://www.opentk.com/node/3430 "Picking example's problem"
The debug.log would be deleted after launching an example, causing the
example browser to complain that the file cannot be found. In reality,
it should be deleted before launching an example - fixed.
Starting with OpenGL 4.1 and the ARB_ES2_compatibility extension, desktop contexts can execute OpenGL|ES code. This fallback will allow platforms to execute OpenGL|ES code even if EGL is not available (e.g. Nvidia/Windows).
Using a separate, isolated process protects against incompatible interactions between the Example Browser (WinForms) and the executing example (native or SDL). It also protects the main GUI from crashes in the example code.
