misc patch to fix position/texcoord attribute index usage

gstglfilter _bind_buffer (line 1522) call VertexAttribPointer before get the 
attrib location, so 

  _get_attributes (filter);

should be called before

   gl->VertexAttribPointer (filter->draw_attr_position_loc, 3, GL_FLOAT,
       GL_FALSE, 5 * sizeof (GLfloat), (void *) 0);
plus, 0 is valid vertex attrib index(-1 is invalid) ,so we should init 
attrib index to -1, and compare with -1 ? if so , this patch fix this.
