This migrates all the GLX window system code down from the Clutter backend code into a Cogl winsys. Moving OpenGL window system binding code down from Clutter into Cogl is the biggest blocker to having Cogl become a standalone 3D graphics library, so this is an important step in that direction.

|
|
* @short_description: Represents a display pipeline
|
|
*
|
|
* TODO: We still need to decide if we really need this object or if
|
|
* it's enough to just have the CoglSwapChain CoglOnscreenTemplate
|
|
* objects.
|
|
*
|
|
* The basic intention is for this object to let the application
|
|
* specify its display preferences before creating a context, and
|
|
* there are a few different aspects to this...
|
|
*
|
|
* Firstly there is the physical display pipeline that is currently
|
|
* being used including the digital to analogue conversion hardware
|
|
* and the screen the user sees. Although we don't have a plan to
|
|
* expose all the advanced features of arbitrary display hardware with
|
|
* a Cogl API, some backends may want to expose limited control over
|
|
* this hardware via Cogl and simpler features like providing a list
|
|
* of modes to choose from in a UI could be nice too.
|
|
*
|
|
* Another aspect is that the display configuration may be tightly
|
|
* related to how onscreen framebuffers should be configured. In fact
|
|
* one of the early rationals for this object was to let us handle
|
|
* GLX's requirement that framebuffers must be "compatible" with the
|
|
* fbconfig associated with the current context meaning we have to
|
|
* force the user to describe how they would like to create their
|
|
* onscreen windows before we can choose a suitable fbconfig and
|
|
* create a GLContext.
|
|
*
|
|
* TODO: continue this thought process and come to a decision...
