+-----------------
+ HIGH PRIORITY
+-----------------
+
+- Correct sharing of data (display lists, texture objects) between
+ contexts. This is different for X vs W32 -- one can be done at
+ runtime, the other requires sharing to be done at context creation.
+ For Win32, see the wglShareLists(). For a GLX platform, see the
+ share parameter to glXCreateContext().
+
+
+- Non-const array types must be properly released with JNI_COMMIT in
+ order to see side effects if the array was copied.
+
+- Finish implementation of <type>** arguments (currently only works
+ for "const char**". This is needed for glMultiDrawElements and
+ one Cg routine.
+
+-----------------
+ MEDIUM PRIORITY
+-----------------
+
+- Figure out how to implement GLEventListener.displayChanged(bool,bool).
+ I believe we need additional support in J2SE before this will be possible
+ to detect and implement. The basic problem is that we need to find a way
+ to determine when a GLCanvas has moved to a different
+ display device, so we can re-load the GL function addresses using
+ wgl/glXGetProcAddress. See comments at top of GLCanvas.java. Also need a
+ way to determine with the display mode (e.g., bit depth) of the GLDrawable
+ has changed. Once both of these problems are solved, we'll need to hook it
+ into GLEventListener.displayChanged() and also be sure to reset the
+ GLDrawable's glProcAddress table as appropriate.
+
+-----------------
+ LOW PRIORITY
+-----------------
+
+- Think about making StructAccessors for e.g. GLUquadric "more opaque"
+
+- Think about e.g. protected access for Impl classes
+
+- Find a way to limit the expansion of void* types to only certain
+ java array types. For example, glCallLists(..., GLenum type, void*)
+ only accepts certain values in its type parameter; it would be nice
+ to limit the expansion to those types.
+
+- Fix glProgramStringARB and glGetProgramString{NV,ARB} so that they
+ use Strings and/or StringBuffers insteead of GLUbyte* and void*
+
+- figure out how to deal with WGL entry points:
+ WINGDIAPI HGLRC WINAPI wglCreateLayerContext(HDC, int);
+ WINGDIAPI BOOL WINAPI wglUseFontBitmapsA(HDC, DWORD, DWORD, DWORD);
+ WINGDIAPI BOOL WINAPI wglUseFontBitmapsW(HDC, DWORD, DWORD, DWORD);
+ see commented-out section in make/stub_includes/win32/wingdi.h
+
+- Need a disciplined mechanism for converting char* argument types. For
+ example, many C functions accept a "char*" argument with the semantic that
+ output data will be written into the buffer pointed to by the
+ argument. The type "const char*" is used when the argument's data will be
+ unchanged. Our system needs a new directive, such as
+ "ArgumentIsStringBuffer" to be used for type conversion in those cases
+ where the native code needs to write output into the "char*" argument. Not
+ sure how to handle this on the native side -- it may require hints to the
+ native code generator as to how large the StringBuffer's backing buffer
+ needs to be, so we can assert this condition before passing the backing
+ buffer to the C function we are wrapping.
+
+- Throw an exception if native calls to GetPrimitiveArrayCritical
+ return null.
+
+- Before emitting functions and constants, sort them first by
+ extension suffix (i.e., ARB, ATI, NV, etc) and then by name. This
+ will organize them in the file more logically. When writing the
+ code, the sort function can check the last substring that's all caps,
+ and treat this as the extension owner. Be careful though, some end
+ in "3D" and that's not an extension.
+
