* An implementation of ThebesLayer that ONLY supports remote

* composition that is backed by tiles. This thebes layer implementation
|
|
* is better suited to mobile hardware to work around slow implementation
|
|
* of glTexImage2D (for OGL compositors), and restrait memory bandwidth.
|
|
*
|
|
* Tiled Thebes layers use a different protocol compared with other
|
|
* layers. A copy of the tiled buffer is made and sent to the compositing
|
|
* thread via the layers protocol. Tiles are uploaded by the buffers
|
|
* asynchonously without using IPC, that means they are not safe for cross-
|
|
* process use (bug 747811). Each tile has a TextureHost/Client pair but
|
|
* they communicate directly rather than using the Texture protocol.
|
|
*
|
|
* There is no ContentClient for tiled layers. There is a ContentHost, however.
