|
|
* This allows libEGL to get the function pointer via dlsym, since it can't
|
|
* directly link against libgui. In a future release, we'll fix this so that
|
|
* libgui does not depend on graphics API libraries, and libEGL can link
|
|
* against it. The current dependencies from libgui -> libEGL are:
|
|
* - the GLConsumer class, which should be moved to its own library
|
|
* - the EGLsyncKHR synchronization in BufferQueue, which is deprecated and
|
|
* will be removed soon.
