* This function should only need to be called in exceptional circumstances.

|
|
* As an optimization Cogl drawing functions may batch up primitives
|
|
* internally, so if you are trying to use raw GL outside of Cogl you stand a
|
|
* better chance of being successful if you ask Cogl to flush any batched
|
|
* geometry before making your state changes.
|
|
*
|
|
* It only ensure that the underlying driver is issued all the commands
|
|
* necessary to draw the batched primitives. It provides no guarantees about
|
|
* when the driver will complete the rendering.
|
|
*
|
|
* This provides no guarantees about the GL state upon returning and to avoid
|
|
* confusing Cogl you should aim to restore any changes you make before
|
|
* resuming use of Cogl.
|
|
*
|
|
* If you are making state changes with the intention of affecting Cogl drawing
|
|
* primitives you are 100% on your own since you stand a good chance of
|
|
* conflicting with Cogl internals. For example clutter-gst which currently
|
|
* uses direct GL calls to bind ARBfp programs will very likely break when Cogl
|
|
* starts to use ARBfb programs itself for the material API.
