Bug Description
In Smalltalk programmed sketch, it will be nice to make the slider helper to work with point defined by block:
- slider return a block of code, value of the slider is get by sending the #value message
- point defined by block expect as argument mathItems, it should handle block of code argument as well.

It should not be necessary as long as slider are not passed as arguments, and there are not reason to do it.
See example bellow:
|figure r u|
figure:=DrGeoCanvas new.
r := figure float: 0.8 at: 0@ -1 from: 0 to: 4 name: 'r' showValue: true.
u := figure pointOnCurve: (figure segment: 0@0 to: 0@1) at: 0.7.
u round small color: Color blue.
1 to: 1000 do: [:n|
u := figure
point: [:parent| |y |
y := parent point y.
(n / 5) @ r value * y * (1 - y)]
parent: u.
u round small color: Color blue].
