    Message : Reland "EGL: GLES: Implement GL_EXT_protected_textures" This is a reland of 6210a9b34a721df2c84cf69170ad9bf7ba40e4aa This removes changes in gl backend. Original change's description: > EGL: GLES: Implement GL_EXT_protected_textures > > Implement EGL_EXT_protected_content Images > Add protected member to Images and Textures > Add error when creating objects if not supported or > does't match native buffer > When creating siblings pass protected state > Add extension caps > Add Validation > Add GetTexParameter and SetTextparameter > Add protected to Texture and state > Expand tests for images and textures > > Test: angle_end2end_test --gtest_filter=EGLProtectedContentTest > > Bug: angleproject:3965 > Change-Id: I35a89b4e80bba6d9b6831c68e71630eef304dacb > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2802852 > Commit-Queue: Mohan Maiya <m.maiya@samsung.com> > Reviewed-by: Geoff Lang <geofflang@chromium.org> > Reviewed-by: Jamie Madill <jmadill@chromium.org> > Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Test: angle_end2end_test --gtest_filter=EGLProtectedContentTest Bug: angleproject:3965 Change-Id: Id36d697c53afc0f0dadf92bda4565f9157f4fc2a Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3076825 Commit-Queue: Brandon Schade <b.schade@samsung.com> Reviewed-by: Ian Elliott <ianelliott@google.com> Reviewed-by: Jamie Madill <jmadill@chromium.org>
