59 | Comments about this class from Gunnar: | - | ||||||||||||
60 | - | |||||||||||||
61 | The QSGContext class is right now two things.. The first is the | - | ||||||||||||
62 | adaptation layer and central storage ground for all the things | - | ||||||||||||
63 | in the scene graph, like textures and materials. This part really | - | ||||||||||||
64 | belongs inside the scene graph coreapi. | - | ||||||||||||
65 | - | |||||||||||||
66 | The other part is the QML adaptation classes, like how to implement | - | ||||||||||||
67 | rectangle nodes. This is not part of the scene graph core API, but | - | ||||||||||||
68 | more part of the QML adaptation of scene graph. | - | ||||||||||||
69 | - | |||||||||||||
70 | If we ever move the scene graph core API into its own thing, this class | - | ||||||||||||
71 | needs to be split in two. Right now its one because we're lazy when it comes | - | ||||||||||||
72 | to defining plugin interfaces.. | - | ||||||||||||
