+///
+/// CompositableTextureRef is a mechanism that lets us count how many

+/// between compositables).

+/// * CompositableHosts that receive UseTexture and similar messages *must*
+/// store all of the TextureHosts they receive in CompositableTextureRef slots
+/// for as long as they may be using them.
+/// * CompositableHosts must store each texture in a *single*
+/// CompositableTextureRef slot to ensure that the counter properly reflects how
+/// many compositables are using the texture. If a compositable needs to hold
+/// two references to a given texture (for example to have a pointer to the
+/// current texture in a list of textures that may be used), it can hold its
