* Structures/Parameter.cs: Avoid qualifying IntPtr fully ((a) it's
unnecessary, since we have "using System;" already and (b) the
namespace qualification is not portable to C++).
Removed global enum, delegate and function collections.
Simplified loading process and removed global Initialize() methods.
Read "count" attributes for function parameters in overrides.xml.
Disabled wgl/glx/glu generators.
Removed large amounts of stale code.
Modified comparison order to place pointer overloads after reference or array overloads. Fixes issue [#1098]: "[Bind] Work around VS bug by ensuring pointer parameters are generated last".
* Main.cs: Removed unused comments. Improved parameter handling. Added -o:keep_untyped_parameters option.
* Settings.cs: Added KeepUntypedEnums compatibility setting.
* Structures/Delegate.cs: Removed stale comments. Refactored CreateWrappers() method to support untyped enum overload generation and simplified method implementation. Replaced CurrentType translations with QualifiedType.
* Structures/Function.cs: Removed stale code. Fixed copy constructors to copy all necessary fields. Use QualifiedType instead of CurrentType in WrapReturnType and CreateBody methods. Made Body statement lists static to improve performance. Added hack to modify callstring casts in keep_untyped_enums wrappers. Generate call string from the Function CreateBody was called on, rather than the current Function (solves issues with invalid casts in specific cases).
* Structures/Parameter.cs: Use fully qualified type instead of current type in several caeses.
* Structures/Type.cs: Added explicit support for fully qualified types.
Added check for the existence of override elements before trying to use them (avoids potential null reference exception).
Regenerated bindings using the latest version of the generator.
Enabled enum overrides in the CL and ES generators.
Function parameters now follow enum overrides (for example, if function Foo takes enum Bar and enum Bar is overriden to Baz, this change will be reflected on function Foo).
Changed default CLGenerator settings to not generate debug helpers.
Made the generation of debug helpers optional. They are currently specific to OpenTK.Graphics and need more work before they can be used with OpenTK.Compute or OpenTK.Audio.
Improved handling of string arrays.
Added handling of flow direction to ESGenerator and Delegate.TranslateParameters().
Moved FlowDirection enum outside of Parameter class.
Replaced all instances of Version14, Version15, Version20, Version30 and Version31 enums by type-safe equivalents.
Added gloverrides.xml to support overrides to function parameters / return types. This will make future spec updates easier to merge.
Improved handling of invalid tokens in the specs.
Bindings are now written in alphabetical order. This will reduce patch size for future updates and make side-by-side comparisons easier to perform.
Added GraphicsContext.ErrorChecking property to temporarily disable error checking if necessary.
Error checking is now added to all functions in debug mode (the generator would miss specific CLS-compliant overloads before).
