Maarten Maathuis 541b25038a exa/mixed: Exclude frontbuffer from deferred pixmap handling.

- Apps like xterm can trigger a lot of fallback rendering.
- This can lead to (annoyingly) high latencies, because you
  have to wait for the block handler.
- You need a driver that doesn't directly access the front
  buffer to trigger this (NV50+ nouveau for example).
- Repeatingly doing dmesg on an xterm with a bitmap font
  will reveal that you never see part of the text.
- I have recieved at least one complaint in the past of slow
  terminal performance, which was related to core font
  rendering.
- This does sacrifice some throughput, roughly 33% slower.
