This introduces support for the following extensions:
- EXT_geometry_point_size
- EXT_primitive_bounding_box
- EXT_texture_array
- EXT_tessellation_point_size
GLboolean is typedefed as an unsigned char. It appears that `[return:
MarshalAs(UnmanagedType.U1)]` is ignored in calli p/invokes, so we need
to take care of this ourselves by emitting byte instead of bool for the
p/invoke signature. The public API remains unchanged.
Fixes issue #129.
According to the OpenGL 4.4 specification, RenderbufferStorage accepts
both generic and sized depth-stencil formats (DepthComponent and
DepthStencil). See sections 9.2.4, 9.2.5 and 9.4.
These break dynamic loading of OpenGL ES and bloat OpenTK.dll with
duplicated strings. The new extension loading mechanism is now fast
enough to make DllImports unnecessary.
We can use DllImports for OpenGL functions <= v1.1 on all platforms,
including Windows. This allows us to reduce the number of required
GetProcAddress calls by 474, reducing startup time and memory
consumption.
This setting can be turned off through Settings.Legacy.UseDllImports
and UseWindowsCompatibleGL.
CSharpSpecWriter now correctly outputs doc summaries on ARB_imaging
functions that do not have a version/deprecation string. Additionally,
it no longer warns about documentation parameter mismatches for
parameters matching C# keywords.
Instead of using xslt, we now process the documentation in code. This
allows us to fix mismatches from e.g. invalid parameter names that
sometimes creep in the specs.
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.)
Instead of inheriting and overriding StreamWriter methods, it now
forwards its parameters to an internal StreamWriter, after applying the
necessary formatting changes.
This shields us from the StreamWriter implementation differences
between .Net and Mono.
Several projects are still using the last svn revision from the
sourceforge repository (r3127). These overloads provide an upgrade path
from r3127 to OpenTK 1.1.
The Mono 2.10 compiler fails when compiling extern methods that are not
marked as DllImport. We fix that by adding a method body that throws a
NotImplementedException instead.
Additionally, MonoDevelop 2.8 cannot open sln files with ToolsVersion 12.
The fix is to change ToolsVersion to 11.
Tools now go to the Binaries/Tools/[Debug|Release] directory. OpenTK
remains at BInaries/OpenTK/[Debug|Release].
Mono.Cecil and IKVM now reside under the Dependencies/managed/
directory.
We should be able to use static pinvokes on platforms that do not
provide or require extensions and calli instructions on platforms with
extension APIs. This dinstiction will be implemented as a parameter in
the rewriter.
By using untyped integers instead of typed integers in the unmanaged
callsites, we allow monolinker to keep the exact set of enums that are
used by the user. Without this, we’d have to keep every single enum in
place to avoid missing type exceptions.
This does not affect the public signatures or the generated code in any
way.
OpenTK normally uses reflection to load bindings, instead of generating
huge constructors. Although reflection is faster on first load (thanks
to reduced JIT overhead), it fails to work correctly with monolinker.
This branch explores the performance of a direct binding.
Trim regex will now correctly match GetInteger64 and other functions
ending in "64". It also uses a correct ending anchor to avoid matches
in the middle of a function name.
Scan through the list of wrappers once, instead of multiple times, in
order to find out which functions use which enums. This speeds up enum
generation tremendously.
GetBoolean, GetInteger6, GetFixedvOES and Delete* are now matched in
the convenience wrapper generator. Methods returning vectors of fixed
size (e.g. 4 ints) are no longer matched.
The lookup for function overrides and overloads now tries to work
around extension case mismatches (e.g. IBM vs Ibm). This fixes a few
specific cases of missing overrides.
It is now possible to specify multiple overloads for the same function.
This is helpful for maintaining backwards compatibility with previous
releases.
OpenTK 1.0 and Xamarin Android/iOS do not use strongly-typed enums for
OpenGL ES. Generate overloads with the "All" enum in order to maintain
compatibility.
Only Get*, Gen*, Delete* and New* functions get convenience overloads.
This avoids issues with functions such as Rect() that have similar
signatures but cannot use such overloads.
This restriction will be relaxed in the future.
These are convenience parameters for function receiving a size and an
array parameter, like DeleteTextures(int n, int[] ids). The generator
will now add overloads taking a single parameter, such as
DeleteTexture(int id).
