+ [iOS] PDFDocumentImage should cache only a sub image of the PDF when caching the whole image is expensive
+ https://bugs.webkit.org/show_bug.cgi?id=158715
+
+ Reviewed by Dean Jackson.
+
+ Test: fast/images/displaced-non-cached-pdf.html
+
+ For iOS, we need to ensure the size of the cached PDF images will not
+ exceed some limit. Also we should be caching only a sub image of the PDF
+ if caching the whole image will exceed the memory limit.
+
+ * page/Settings.cpp:
+ (WebCore::Settings::Settings):
+ (WebCore::Settings::setCachedPDFImageEnabled):
+ * page/Settings.h:
+ (WebCore::Settings::isCachedPDFImageEnabled):
+ Add an option to disable caching the PDF images.
+
+ * platform/graphics/cg/PDFDocumentImage.cpp:
+ (WebCore::PDFDocumentImage::setCachedPDFImageEnabled):
+ Allow the caller of draw() to disable caching the PDF images.
+
+ (WebCore::PDFDocumentImage::cacheParametersMatch):
+ Match the context dirty rectangle with the cached image rectangle.
+
+ (WebCore::transformContextForPainting):
+ When preparing the context for drawing the PDF, take the location
+ of the destination rectangle into account. We do not need to scale
+ the location of the source rectangle because we scale the size of
+ the rectangle but we don't scale the whole coordinate system.
+
+ (WebCore::cachedImageRect):
+ Calculate the rectangle of the cached image such that it does not
+ exceed the limit. Start from the center of the dirty rectangle and
+ then expand around it.
+
+ (WebCore::PDFDocumentImage::decodedSizeChanged):
+ In addition to notifying the ImageObserver, it keeps track of the size
+ of all the cached PDF images.
+
+ (WebCore::PDFDocumentImage::updateCachedImageIfNeeded):
+ Ensure the size of all the cached images does not exceed the limit
+
+ (WebCore::PDFDocumentImage::destroyDecodedData):
+ * platform/graphics/cg/PDFDocumentImage.h:
+
+ * rendering/RenderImage.cpp:
+ (WebCore::RenderImage::paintIntoRect):
+ Pass the option to disable caching the PDF images to PDFDocumentImage.
+
+ * testing/InternalSettings.cpp:
+ (WebCore::InternalSettings::Backup::Backup):
+ (WebCore::InternalSettings::Backup::restoreTo):
+ (WebCore::InternalSettings::setCachedPDFImageEnabled):
+ * testing/InternalSettings.h:
+ * testing/InternalSettings.idl:
