  Message : ANGLEPerfTest: Skip tests when missing color space support. Make tests where a non-linear colorspace was requested on platforms that do not support EGL_KHR_gl_colorspace non-fatal. Add a initializeGLWithResult function to GLWindowBase, returning a new GLWindowResult enum and wrap it in EGLWindow and WGLWindow. Bug: angleproject:6366 Change-Id: Ib57327c4d988d82064272f229f8ad59287541623 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3151833 Commit-Queue: Lubosz Sarnecki <lubosz.sarnecki@collabora.com> Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Cody Northrop <cnorthrop@google.com>
