*
|
|
* When an object needs a dynamic texture, it checks it out using CheckOutTexture(), passing
|
|
* the resolution of the texture it needs. When the object is done with the texture, it
|
|
* calls CheckInTexture(). New dynamic textures can be allocated by calling CreateDynamicTexture,
|
|
* but these textures will be unmanaged.
