-// Some ideas on how clouds should work
-//
-// Each region has a cloud layer
-// Each cloud layer has pre-allocated space for N clouds
-// The LLSky class knows the max number of clouds to render M.
-// All clouds use the same texture, but the tex-coords can take on 8 configurations
-// (four rotations, front and back)
-//
-// The sky's part
-// --------------
-// The sky knows that A clouds have been assigned to regions and there are B left over.
-// Divide B by number of active regions to get C.
-// Ask each region to add C more clouds and return total number D.
-// Add up all the D's to get a new A.
-//
-// The cloud layer's part
-// ----------------------
-// The cloud layer is a grid of possibility. Each grid's value represents the probablility
-// (0.0 to 1.0) that a cloud placement query will succeed.
-//
-// The sky asks the region to add C more clouds.
-// The cloud layer tries a total of E times to place clouds and returns total cloud count.
-//
-// Clouds move according to local wind velocity.
-// If a cloud moves out of region then it's location is sent to neighbor region
-// or it is allowed to drift and decay.
-//
-// The clouds in non-visible regions do not propagate every frame.
-// Each frame one non-visible region is allowed to propagate it's clouds
-// (might have to check to see if incoming cloud was already visible or not).
-//
