+// Caret policy, used by SetXCaretPolicy and SetYCaretPolicy.
+// 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.
+#define wxSTC_CARET_SLOP 0x01
+
+// 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.
+#define wxSTC_CARET_STRICT 0x04
+
+// 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.
+#define wxSTC_CARET_JUMPS 0x10
+
+// 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.
