What happens if we draw to the base of a texture that has mips? Don't we still
need to regenerate in that case? Maybe we need a test for this case?

You are right. Last night, while writing this, I thought "the user will provide
all the mipmap levels." But that isn't the case for rendered-to content. We had
already mentioned that and I forgot last night.

 
     enum MipMapsStatus {
         kNotAllocated_MipMapsStatus,
-        kAllocated_MipMapsStatus,
-        kValid_MipMapsStatus
+        kAllocated_MipMapsStatus
     };
 
     MipMapsStatus   fMipMapsStatus;
-    // These two shift a fixed-point value into normalized coordinates  
+    // These two shift a fixed-point value into normalized coordinates
     // for this texture if the texture is power of two sized.
     int             fShiftFixedX;
     int             fShiftFixedY;
 
     friend class GrTexturePriv;
 
     typedef GrSurface INHERITED;
 };
