Subject: [PATCH 06/58] egl: optimise eglMakeCurrent for the case where nothing
|
|
has changed
|
|
|
|
When an application calls eglMakeCurrent with a context, draw surface and
|
|
read surface that match those that are currently bound to the calling
|
|
thread don't perform a flush as this is an expensive operation.
