<pre>The r203378 did not actually fix the <a class="bz_bug_link

title="RESOLVED FIXED - [iOS] PDFDocumentImage should cache only a sub image of the PDF when caching the whole image is expensive"
href="show_bug.cgi?id=158715">https://bugs.webkit.org/show_bug.cgi?id=158715</a> because although we have the right steps to decide whether to cache the PDF image or not, we are using the unscaled size which is wrong. The image has to be created scaled with the context.scaleFactor(). This may lead to allowing caching a PDF image which will cause the WebKit to jetsam on iOS.</pre>
