Source/WebCore: 

Patch by Jia Pu <jpu@apple.com> on 2011-02-03
This patch includes fix for reported bug, and also some housekeeping changes.

To implement desired behavior, we need:
1. Add a new marker type, SpellCheckingExemption, since now we distingusish between text
   that shouldn't be spellchecked and text shouldn't be autocorrected.
2. Make sure that there is no pending correction panel when we enter markAllMisspellingsAndBadGrammarInRanges().
   Otherwise the spell checking code in that function may interfere with autocorrection. This
   is achieved by explicitly applying pending correction when user types space, line break or
   paragraph break.

Housekeeping code changes include:
1. Change manual-tests that were broken by relocated WebCore directory.
2. Use TextIterator in various DocumentMarkerController functions instead of using
   Node::traverseNextNode() directly.
3. Allow passing multiple marker types into DocumentMarkerController::removeMarkers() and
   DocumentMarkerController::hasMarkers() to improve clarity and efficiency.
4. Fixes of minor bugs that were exposed previously.

* WebCore.exp.in: Change signature of DocumentMarkerController::removeMarkers().

* dom/DocumentMarker.h: Added new marker type SpellCheckingExemption.

* dom/DocumentMarkerController.cpp:
(WebCore::DocumentMarkerController::removeMarkers): Use TextIterator to scan the range to be
   consistent with addMarker() function. Allow passing in multiple marker types in one call.
   Added a boolean argument to specify the behavior when removing markers that partially
   overlap the specified range.
(WebCore::DocumentMarkerController::removeMarkersFromMarkerMapVectorPair): Allow passing in
   multiple marker types in one call.
(WebCore::DocumentMarkerController::hasMarkers): Use TextIterator to scan the range to be
   consistent with addMarker() function. Allow passing in multiple marker types in one call.

* dom/DocumentMarkerController.h: Allow passing in multiple marker types to removeMarkers()
   and hasMarkers(). Added a boolean argument to removeMarkers() to specify the behavior when
   removing markers that partially overlap the specified range.

* editing/Editor.cpp:
(WebCore::markerTypesForAutocorrection): Add SpellCheckingExemption marker when apply correction.
(WebCore::markerTypesForReplacement): Ditto.
(WebCore::Editor::respondToChangedSelection): Reordered call to dismissCorrectionPanel() and
   setSelection() to make sure there is no pending correction when entering
   markAllMisspellingsAndBadGrammarInRanges().
(WebCore::Editor::appliedEditing): Only remove CorrectionIndicator markers when the command
   is a top level command to improve efficiency.
(WebCore::Editor::insertTextWithoutSendingTextEvent): Added code to applying pending correction.
(WebCore::Editor::insertLineBreak): Ditto.
(WebCore::Editor::insertParagraphSeparator): Ditto.
(WebCore::Editor::markAllMisspellingsAndBadGrammarInRanges): Don't mark mispelling if the
   text carries SpellCheckingExemption marker.
(WebCore::Editor::correctionPanelTimerFired): Reset correction panel if the returned suggestion
   from spellchecker is an empty string.
(WebCore::Editor::removeSpellAndCorrectionMarkersFromWordsToBeEdited):
   Use new DocumentMarkerController::removeMarkers() to replace custom implemenation to improve
   efficiency and readability.
(WebCore::Editor::applyCorrectionPanelInfo): Remove the code that set caret position after
   applying correction, since it's unnecessary. Also, store pre-correction string together with
   the marker for reversion panel to use.
(WebCore::Editor::applyAutocorrectionBeforeTypingIfAppropriate): Apply pending correction.
(WebCore::Editor::changeSelectionAfterCommand): Moved marker removal code to Editor::appliedEditing()
   where we have access to EditCommand object.

* editing/Editor.h: Added new function applyAutocorrectionAfterTypingIfAppropriate().

* manual-tests/autocorrection/autocorrection-cancelled-by-ESC.html: Change manual-tests that
   were broken by relocated WebCore directory.

* manual-tests/autocorrection/autocorrection-cancelled-by-typing-1.html: Ditto.

* manual-tests/autocorrection/autocorrection-contraction.html: Ditto.

* manual-tests/autocorrection/continue-typing-to-dismiss-reversion.html: Ditto.

* manual-tests/autocorrection/delete-to-dismiss-reversion.html: Ditto.

* manual-tests/autocorrection/delete-to-end-of-word-to-show-reversion.html: Ditto.

* manual-tests/autocorrection/dismiss-multiple-guesses.html: Ditto.

* manual-tests/autocorrection/move-to-end-of-word-to-show-reversion.html: Ditto.

* manual-tests/autocorrection/select-from-multiple-guesses.html: Ditto.

* manual-tests/autocorrection/spell-checking-after-reversion.html: Added.

* manual-tests/autocorrection/type-whitespace-to-dismiss-reversion.html: Change manual-tests that
   were broken by relocated WebCore directory.

* rendering/InlineTextBox.cpp:
(WebCore::InlineTextBox::paintDocumentMarkers): Code clean-up to be more concise.
