380 For better usage of the LayerManagement Service from application
381 point of view an additional C-API is implemented (see LayerManagerClient/ilmClient).
382 This API is deployed as shared libraries an can be linked to the application
383 which will controll the service. For the internal communication between the client
384 and the service D-BUS is used.
388 To support hardware layers and to get a better interoperability with other applications
389 and platforms the API was extended by the following features :
391 * Layer and Surface and Group Ids can be applied by from the client side too.
392 * IlmMatrix class is now available in the LayerManagerUtils library, to support
393 simple 3D / 2D transformations
395 3. Implementation of the open use case "make a screen shot"
397 The use case "make a screen shot" was still open and is now implemented
400 4. Example applications
402 Several example applications were added to demonstrate the usage and capabilities of
405 * EGLX11ApplicationExample - Rotating triangle which is registered to the service.
406 * LayerManagementClientExample - Example for controlling the service and the rendered layers.
407 * LayerSceneDescriptionExample - Example for the definition of external layer and surface ids.
411 * Race condition during access/creation/deletion of data in layer list removed.
412 * Layer and surface compositing in GLESGraphicSystem improved
