//The isOpaque() function gives a hint about whether the texture is opaque,
//so the drawing can be done faster.

//This is the current texture hierarchy:
//
//Texture
//-- ColorTexture
//-- FadeInTexture
//-- BasicTexture
// -- UploadedTexture
//    -- BitmapTexture
//    -- Tile
//    -- ResourceTexture
//       -- NinePatchTexture
//    -- CanvasTexture
//       -- StringTexture
