Neil Roberts da3be3df6b cogl-material: Add support for point sprites
This adds a new API call to enable point sprite coordinate generation
for a material layer:

void
cogl_material_set_layer_point_sprite_coords_enabled (CoglHandle material,
                                                     int layer_index,
                                                     gboolean enable);

There is also a corresponding get function.

Enabling point sprite coords simply sets the GL_COORD_REPLACE of the
GL_POINT_SPRITE glTexEnv when flusing the material. There is no
separate application control for glEnable(GL_POINT_SPRITE). Instead it
is left permanently enabled under the assumption that it has no affect
unless GL_COORD_REPLACE is enabled for a texture unit.
