Zoom while drawing: Strange behavior of the cursor.

[jorix]

Using mobile devices (small screens) is very useful to zoom while drawing.

When zoom (in or out) the insertion point is separated from the drawing if you have previously made ​​a pan.

Tested on iPad.

In Handler.Path.addPoint this.point is removed but not added, this was the problem. A single line!

Tests are added.

Very good patch! One thing though: Measure test_cancel fails with your patch applied:

test_cancel  fail 1 ok 3
ok calling cancel before drawing works
ok control remains active after cancel
fail feature persists. eq: values differ: got 2, but expected 1
ok feature is gone after cancel

It would be great if you could investigate this problem.

The cause of the problem surprised me.

This afternoon I looked at it test controls.

I've done several tests with the examples/measure.html (yesterday and today) and everything goes correctly (but see NOTE).

In tests/control/measure.html missing trigger("dblclick", 10, 10); but this before "pan while dragging" and did not affect the test because the bug r8831 is before this test r9225.

So, in attachment:3195.2.patch I changed tests/measure.html

Tested in: IE8, EI6, Chrome-10, Safari. But in FF3.6.15 everything works except handler/box.html (fails with or without patch)

NOTE: Double click sometimes fails in IE8 without <!DOCTYPE > (try lines with many points or polygons). For example fails in examples/measure.html (see description of this bug in #3194)

Please review.

NOTE: Before #3195 tests/measure.html worked also when persist: false, so it was not a proper test.

I neglected to say that I passed the tests for all controls and handlers.

(In [11836]) when drawing make sure the point follow the cursor, even after zooming in or out, p=jorix, r=me (closes #3195)
