[vlc-devel] [PATCH] vout: do not blend SPU early based on resolution

[Rémi Denis-Courmont]

In general, the best SPU quality should be achieved by rendering
directly to the intended display resolution rather than scaling.

This also avoids certain problems:

- If there is no blending for the source chroma, blending fails
  depending on the display resolution. This is a real problem now with
  opaque chromas and "weird" high-depth chromas.
- If the source resolution is really large, rendering to it is a waste
  of processing power.
