Evaluate still changes your max_gradient: is it supposed to work this way?
#include "functions.inc"
#declare f_granito = function {pigment {granite color_map {[0 rgb 0][1 rgb
1]} scale 50} }
isosurface {
function {f_rounded_box (x,y,z,2,15,10,15)+f_granito (x,y,z).red*1.25}
accuracy 10^-2
max_gradient 2
evaluate 1,10,0.99
contained_by {box {-<15,10,15>,<15,10,15> }}
translate <15,10,15>*<1,1,-1>
pigment {rgb 0.7}
scale 1.5
}
light_source {<100,100,-100> rgb 1.5}
camera {
location <20,50,-100> look_at 15*x}

In beta 8 the dynamic max_gradient method is always activated if
'evaluate' is used, i don't really know what's the difference between only
evaluate and evaluate+max_gradient now, but it is no more needed for
getting the estimated value printed as a warning.

Yes, 'evaluate' is the dynamic max gradient method now. the documentation
has not been fully updated and the output of the warnings when 'evaluate' is
used is not perfect yet. There is going to be some more fine-tuning for the
'evaluate' warnings. However, the max gradient warnings without evaluiate
are correct as long as they aren't zero. The output of zero will be
eliminated in a future beta.

Shouldn't its name be changed?
Or the max gradient method still 'evaluates' something?

It is still the same method, 'evaluate' is a good name for it.
