/** |

* Class which represents a OpenGL Framebuffer object. |
| ... | ... | |
| 29 | 32 |
* User is able to create either WRITE-only Framebuffers from objects already constructed outside |
| 30 | 33 |
* of the library (the first constructor; primary use case: the screen) or an offscreen READ-WRITE |
| 31 | 34 |
* FBOs (used by the DistortedNode, but also can be used by external users of the library) |
| 35 |
* |
|
| 36 |
* Also, keep all objects created in a static LinkedList. The point: we need to be able to mark |
|
| 37 |
* Framebuffers for deletion, and delete all marked objects later at a convenient time (that's |
|
| 38 |
* because we can only delete from a thread that holds the OpenGL context so here we provide a |
|
| 39 |
* framework where one is able to mark for deletion at any place and actual deletion takes place |
|
| 40 |
* on the next render). |
