CARET constant

CARET_SLOP
If CARET_SLOP is set, we can define a slop value: caretSlop.
This value defines an unwanted zone (UZ) where the caret is... unwanted.
This zone is defined as a number of pixels near the vertical margins,
and as a number of lines near the horizontal margins.
By keeping the caret away from the edges, it is seen within its context,
so it is likely that the identifier that the caret is on can be completely seen,
and that the current line is seen with some of the lines following it which are
often dependent on that line.

CARET_STRICT
If CARET_STRICT is set, the policy is enforced... strictly.
The caret is centred on the display if slop is not set,
and cannot go in the UZ if slop is set.

CARET_JUMPS
If CARET_JUMPS is set, the display is moved more energetically
so the caret can move in the same direction longer before the policy is applied again.

CARET_EVEN
If CARET_EVEN is not set, instead of having symmetrical UZs,
the left and bottom UZs are extended up to right and top UZs respectively.
This way, we favour the displaying of useful information: the begining of lines,
where most code reside, and the lines after the caret, eg. the body of a function.

SetXCaretPolicy (caretPolicy, caretSlop)

Set the way the caret is kept visible when going sideway.
