Bug 766683: Burn Mode on Paint tools are producing artefacts
...
This operation produces NAN (0 / 0) and division
by zero when a layer component is zero.
Inline CLAMP to make sure it swallows also NAN.
A NAN is mapped to 1 for backward compatibility.
[the 2variate function comp (in[b], layer[b]) is
discontinuous at layer[b] = 0]

app: clamp blended results for some compositing ops
...
Quite probably we shouldn't even clamp at the end, not doing that would speed
up compositing. See bug 744265.

app: Change the opacity param of _pixels to gfloat
...
All the internal math is float, and avoiding the conversion
from double is much faster when using SSE math.

Extract layer mode blend functions form their operations so
they can be used directly by paintcore.
