 debug and validation purpose.  One or more XGL entrypoints can be defined in your Layer
 library.  Undefined entrypoints in the Layer library will be passed to the next Layer which
 may be the driver.  Multiple layer libraries can be chained (actually a hierarchy) together.

+xglEnumerateLayer can be called to list the available layer libraries.  xglGetProcAddr is
 used internally by the Layers and ICD Loader to initialize dispatch tables. Layers are
 activated at xglCreateDevice time. xglCreateDevice createInfo struct is extended to allow
 a list of layers to be activated.  Layer libraries can alternatively be LD_PRELOADed.
 
 Layer library example code:
-layer/basic_plugin.c  - simple example
