Description Cyrille Berger 2010-11-21 11:28:53 UTC

KisBufferStream classes should have a deterministic way of settings the "undefined" bits.
For instance, when the flow is 6bits.
upermask = 0b11111100
lowermask = 0b11
value = (value & upermask) + ( value >> 6 & lowermask);

Or something like that.

These files are exceedingly rare, outside test suites, but Dmitry wants to add a warning _if_ the user loads it.

Sorry, we will not in the near future get down to this.
