+Subject: Don't TexImage via GPU when OOP raster is disabled on Windows.
+
+For some reason it's much slower than the the non-GPU based path. The
+test page https://koush.github.io/webcodecs/ goes from ~270fps decoding
+and ~5fps rendering to ~300fps decoding and >> 60fps rendering when
+running with --disable-oop-rasterization.
