Please talk to the relevant GTK devs (CCing several) about this before working on it as I highly doubt this would be acceptable for us; we surely want the system GLES from mesa, not ANGLE's? 1262477 4 achristensen 2016-12-22 17:18:00 -0800 Don't worry, ANGLE's GLES "implementation" is just a checked wrapper and would use the system GLES as its backend. For example, a call to getActiveAttrib from JavaScript currently does checks in GraphicsContext3D::getActiveAttrib and GraphicsContext3D::getActiveAttribImpl and then calls ::glGetActiveAttrib which calls whatever OpenGL/OpenGLES implementation the system has. With the upcoming architecture, a call to getActiveAttrib would call ANGLE's gl::GetActiveAttrib, which would do checks similar to what we have in GraphicsContext3D::getActiveAttrib and GraphicsContext3D::getActiveAttribImpl inside of ANGLE and then ANGLE would call the system's ::glGetActiveAttrib. I have a proof of concept working on Mac. It's pretty terrible right now, but once it gets in better condition I'll show it to Žan et al. 1262494 5 mcatanzaro 2016-12-22 17:49:52 -0800 OK, that sounds fine indeed! 1262495 6 achristensen 2016-12-22 17:59:19 -0800 I have no idea how this will work with wayland, but I'm hoping Žan can help out with that once I have something working cleanly and passing more than the most basic of tests. 1262544 7 cgarcia 2016-12-23 02:03:51 -0800 (In reply to comment #4) > Don't worry, ANGLE's GLES "implementation" is just a checked wrapper and > would use the system GLES as its backend.

That's probably ok, but need to either never include eglplatform.h from ANGLE or update it, because the eglplatform.h from current ANGLE doesn't have the Wayland types. 1263468 8 achristensen 2017-01-03 10:43:11 -0800 We can put whatever we want in our copy of the ANGLE headers, but that sounds like something the ANGLE project would be interested in. You could probably push a change to https://github.com/google/angle/blob/master/include/EGL/eglplatform.h 297679 2016-12-22 15:11:25 -0800 2016-12-22 15:12:05 -0800 Patch
