Scalar Script component and/or Scalar Math components

All too often I run into a wall when I want to run some math on scalar values and feed it into one of the gray scalar inputs. Generally it's simple stuff that the remapping feature doesn't help with, like taking the reciprocal of an input or multiplying two related inputs together, once in a while it's more complicated, like with a parametric equation.

Unfortunately... the only math and scripting component options I have output as maps instead of scalars, so this just simply isn't possible. This has thwarted many a fledgeling filter idea floating around in my brain, as the prospect of recoding several existing filter forge components within a Lua script has all too often just not seemed worth it.

My ideal wish list would include, in order of priority:
1) a Scalar Script (gray output)
2) parallels for each of the RGB Math components with scalar (gray) inputs and outputs
3) a Curve Sample and Map Sample component that allow you to specify a curve/map and a value/point and convert it to a scalar (as previously discussed in http://www.filterforge.com/forum/read...&TID=10109 )
