    • Disable use of FlipEx for problematic use cases. · 585b3d0e
      nduca@chromium.org authored 
      It seems that DWM will, when given an HWND that has an associated
FlipEX swap chain, stretch the contents of the HWND to fill the new
window IF you don't issue draw calls to that HWND before the WM_PAINT
returns. This leads to horrendous sizing artifacts.

For Chromium, this is a show stopper.

But, FlipEx is definitely a good thing, for regular single process
applications.

So, is there a clean way to conditionally disable FlipEX for
these problem cases? The heuristic in this patch basically says "if your hwnd
is not in-process, then you're probably not painting in its HWND, so don't sue
FlipEX."

This catches the Chromium use case. There is still the possibility of a regular
single-process EGL application that tries to draw outside WM_PAINT that would
experience sizing artefacts. But, maybe that's OK.

Anyways, I'm not married to this technique. Just throwing something out there
to start the discussion. :)

      Add support for eglCreatePbufferFromClientBuffer, taking as input a D3D share handle corresponding to the enum EGL_D3D_TEXTURE_2D_SHARE_HANDLE_ANGLE. No spec as of yet, but it does the obvious thing.

    • Use SSE2 to swizzle RGBA to BGRA · f1f28c80
      jbauman@chromium.org authored 
      Using SSE2 can drastically reduce the amount of time it takes to do glTexImage2D. I've also added a plain-C path that's much faster than the one that was there before.

UpdateViewportCache looks like it might be low hanging fruit as well.
