+    Clump has_refs - follow up to commit 63f74ce6<br>
+<br>
+    The function save_set_new() (where the original fix for 'has_refs' is located)<br>
+    is called in two circumstances: when creating a save level, and when destroying<br>
+    a save level.<br>
+<br>
+    We have to retain the 'has_refs' value for the latter case for the garbager to<br>
+    function correctly, but doing so in the former results in the garbager<br>
+    sometimes scanning more memory than is really necessary (it can end up scanning<br>
+    ref memory from the previous save state, which is pointless since that cannot<br>
+    change).<br>
+<br>
+    This change means that 'has_refs == true' will only be retained in the<br>
+    'destroying a save level' case (which works correctly because, by the time the<br>
+    function is called, we've already returned the relevant allocated to its<br>
+    previous state).<br>

+    Fix bug 697097. SMask subpixel offset must match image offset.<br>
+<br>
+    The dda used to select the source pixel for mapping into the image<br>
+    must use the same stepping for gray (monochrome) and color images<br>
+    since an SMask is monochrome and the image may be in color. This is<br>
+    primarily evident with the bug file since Matte is used to indicate<br>
+    that the source data is premuliplied. Colors can shift a LOT since<br>
+    the removal of the premultiplication can expand mistaked.<br>

+<p>
+    PDF interpreter - fix for GSView 5<br>
+<br>
+    Commit 093bd18bd923644fcd25c507088c0ebc63b4c320 included an<br>
+    'optimisation' to prevent rescanning for transparency if we had already<br>
+    scanned. However, this assumed that the function pdfshowpage_setup<br>
+    had already been executed in order to set a variable.<br>
+<br>
+    This is always true when running files via Ghostscript, but any<br>
+    application (such as GSView 5) which executes the PDF operations<br>
+    individually need not execute this function. If the function was not<br>
+    executed then an error occurred. From other comments in pdf_main.ps<br>
+    its possible that customers may be using these functions as well (see<br>
+    the comments above the definition of /pdfshowpage)<br>
+<br>
+    This commit checks to see if the variable has been set, if it has then<br>
+    it is used, otherwise we rescan for transparency. This prevents the<br>
+    error, but uses the optimisation if its possible to do so.<br>
+<br>
+    No differences expected<br>
