Render.c: Improve situation for multiple trapezoid requests.
This change improves the situation in nxagent for the following
issue:
```
"XRenderCompositeTrapezoids builds RenderTrapezoids requests to composite the
specified list of trapezoids to dst. XRenderCompositeTrapezoids will split
the list of trapezoids to build requests no larger than the maximum request
size supported by the server. This can create rendering artifacts as the
precompositing done by RenderTrapezoids when a maskFormat is specified
cannot span multiple requests."
```

Fixes ArcticaProject/nx-libs#336.
