sl@0
|
14 |
// This class does performance tests for eglSwapBuffers() and eglSwapBuffersRegionNOK().
|
sl@0
|
15 |
// The function eglSwapBuffersRegionNOK() is a vendor specific EGL extension and allows users to
|
sl@0
|
16 |
// perform region based surface updates. The test should show how the performance of the
|
sl@0
|
17 |
// extension function compares to the default one.
