For Chris's benefit : it means that the context that was being used is
stored, and restored after qmask. so the FG and BG that you were
previously using return.

That depends on what mask color you set. Set black or white instead of
the default red, does that help?

For QMask (which is an editing mode), certainly. For 'paint modes' (eg
multiply, screen, dissolve), it would be fast; I suspect it would also
be confusing for novices. I would definitely like it as an option,
because I almost never want the same colors for drawing in Multiply
mode or Grain Merge mode as I do for drawing in Normal mode.
Let's review the paint modes:
1. Normal, Dissolve, Behind, Color erase.
2. Overlay, Soft light, Hard Light, Grain Merge, Grain Extract
3. Multiply, Divide, Screen
4. Difference, Addition, Subtract, Dodge, Burn
5. Darken, Lighten, Hue, Saturation, Color, Value
Each number represents a group of paint modes, in which a given color
has more or less the same meaning.
1. Direct color change.
2. Linear color change
3. Cumulative color change
4. Linear one-way color change
5. Direct partial color change (effects only some components)
Surely some people disagree with me here. I expect that, as GEGL
approaches, this sort of control will become more important. Now, I'm
talking about sharing color settings between each group of paint
modes; Later, it will become sharing (X) settings between different
Ops (since gegl will greatly diversify the available ways to paint, a
static mode list becomes infeasible). Therefore I believe that a
facility that allows the user to group modes which will share contexts
is the way to go for future compatible handling of this issue.

This is a good idea! Does anyone know how to do it non-hackishly? Is
new support code needed?
