WebGL array names; uniform* arrays

Let's get rid of support for JS arrays entirely here, for consistency.  We might have to put it back later once we figure out how to fast-path things, but for now let's leave them out.

Also, in each

+        if (glTypeConst == LOCAL_GL_INT) {                                    \
+            WebGLIntArray *wga = static_cast<WebGLIntArray*>(v);              \
+            gl->f##glname(idx, wga->NativeCount() / c, ( ptrType *)wga->NativePointer()); \
+        } else if (glTypeConst == LOCAL_GL_FLOAT) {                           \

you still have to check that arrayLen % c == 0, and error out if not.

Also, in the if (glTypeConst == .. ) { } else if (glTypeConst == .. ), add an 

 else {
  return ErrorMessage("Unhandled glTypeConst");

or something so this doesn't bite us if we use it with a different type.

Now with more sleep.
The macro fallbacks should really be compiler errors. The conditional checks are constant so they shouldn't get hit unless the macro was misused.

Only use WebGL arrays; rename constructors.

NativeCount() != c isn't correct -- that means that you can't set more than 1 element.  There's a bug here in that we really should be passing the count in, now that we can create offset/views (or will be able to, anyway).

Also I see the spec still actually allows for sequence<float> etc. for uniform.. but I think that's going to go away?  Not sure, it might make sense to have it, but we can always put it back later.

Actually, let's go with this -- we're missing some arguments there anyway (count, namely) that we're going to need to bring back I think (for the matrix methods).

Argh, no, we have to keep the JS bits as well.  So, recap:

- Split patch into two -- one that does the renaming

For the renaming patch:

- Rename the interfaces as well, otherwise we have a DEBUG assert that fires

For the Uniform*/VertexAttrib* patch:

- Allow for both JS arrays and Canvas*Arrays.

- if a Canvas*Array is specified, check ->NativeType() on it before doing the static_cast (or QI, but NativeType() check should be faster... even if we get a bogus xpconnect-generated object here, since NS_ERROR_* won't ever be a valid GL type)

- for uniformMatrix*, use % 0 to check that the length is correctly divisible, not == 0; we have to infer the count correctly here (and could have multiple matrices we're loading)
