示例1: Begin
void
OpaqueRenderer::End()
{
mSurface = nullptr;
// gfxWindowsSurface returned from ::Begin() should be released before the
// texture is used. This will assert that this is the case
#if 1
if (mD3D9ThebesSurface) {

nsrefcnt c = mD3D9ThebesSurface->Release();
if (c != 1)
NS_RUNTIMEABORT("Reference mD3D9ThebesSurface must be released by caller of Begin() before calling End()");
}
#endif
