[Spice-devel] [PATCH spice-common v2] canvas_base: Allow to specify constant operations

[Frediano Ziglio]

There's no need for the canvas operations to be changed.
This allows without casts to have the operation structures
constants in the code.
This potentially allows to reduce attack surface having some
more data constant instead or read/write.
