patch_for_is_interleaved_arrays

When I tried to resolve a ogl conformance test ”api-color” issue, I found is_interleaved_arrays function need a small change, patched is attached. 

In the following case, vertex array is not living in a VBO, while color array is living in a VBO, and their stride is same. It is not a interleaved array, but function is_interleaved_arrays will return GL_TRUE. 

I add “abs(arrays[mesaAttr]->Ptr - firstAddr) > firstStride” conditional statement for that case. 

 
glVertexPointer (2, GL_FLOAT, 0, vbuf);
glEnableClientState (GL_VERTEX_ARRAY);

……

glGenBuffersARB(2, array_id);
glBindBufferARB(GL_ARRAY_BUFFER_ARB, array_id[0]);
glColorPointer (attr[apiType].dim, attr[apiType].type, stride, 0);
glEnableClientState (GL_COLOR_ARRAY);
glBufferDataARB(GL_ARRAY_BUFFER_ARB, MAX_STRIDE * 4 * sizeof(char), cbuf, GL_STATIC_DRAW_ARB);

……

glDrawArrays (GL_QUAD_STRIP, 0, 4);
