/* In WGL both color, depth and stencil are features of a pixel format. In case of D3D they are separate.
|

* You are able to add a depth + stencil surface at a later stage when you need it.
|
|
* In order to support this properly in WineD3D we need the ability to recreate the opengl context and
|
|
* drawable when this is required. This is very tricky as we need to reapply ALL opengl states for the new
|
|
* context, need torecreate shaders, textures and other resources.
|
|
*
|
|
* The context manager already takes care of the state problem and for the other tasks code from Reset
|
|
* can be used. These changes are way to risky during the 1.0 code freeze which is taking place right now.
|
|
* Likely a lot of other new bugs will be exposed. For that reason request a depth stencil surface all the
|
|
* time. It can cause a slight performance hit but fixes a lot of regressions. A fixme reminds of that this
|
|
* issue needs to be fixed. */
