Added a default argument to CurveView::drawCurve : a function to initiate the
memoization of continuous functions. The function is implemented in
ContinuousFunctionCache and provided by GraphView. This should be invisible
to other types of curves that rely on CurveView::drawCurve.

Method InteractiveCurveViewRange::panToMakePointVisible now moves the
range of a whole number of pixels when panning horizontally. This allows
the cache of cartesian functions not to be invalidated.

Changed TextFieldFunctionTitleCell::reloadCell to solve an issue with
the alignment of a function's name and definition when changing the
expression :
- typing u_n = (1/3)/2 then changing to u_n = 1/(2/3) without erasing
the formula first. u_n would no longer be aligned with the = sign.

Add the possibility to use a double-typed evaluator when tracing a
curve, useful when errors caused by float approximation mess with the
drawing.

update the bufferSize before setting the text
This fixes the following bug: add a function, rename it "f123456",
change its type to a polar function, rename it --> crash
In file: epsilon/apps/graph/base.nl.i18n some text would look better if placed slightly to the left. I'm talking about lines 23 and 24: SelectLowerBound and SelectUpperBound
This is unfortunately required in several cases:
- Sometimes when we use either float and double (this should be changed)
- Because KDCoordinate is not an int, so any arithmemtic promotes it to
an int
- Because we mix pointer differences and ints
At the moment ViewController::viewWillAppear doesn't do anything, so
there is no real impact. But if we want to use it it needs to be called
from subclasses.
Scenario
Create an empty f function
Create g(x) = 1/x
Go to the graph
Change f(x) to f(theta) = theta^2 + 3
Go back to the graph -> the axes computation was very long
