This simply extends the already existing caching of processed resources to avoid duplicated parsing of 'ExtGState's, which should help with badly generated PDF documents. This patch was tested using the PDF file from issue 6961, i.e. https://github.com/mozilla/pdf.js/files/121712/test.pdf, with the following manifest file: ``` [ { "id": "issue6961", "file": "../web/pdfs/issue6961.pdf", "md5": "", "rounds": 200, "type": "eq" } ] ``` which gave the following *overall* results when comparing this patch against the `master` branch: ``` -- Grouped By browser, stat -- browser | stat | Count | Baseline(ms) | Current(ms) | +/- | % | Result(P<.05) ------- | ------------ | ----- | ------------ | ----------- | --- | ----- | ------------- Firefox | Overall | 400 | 1063 | 1051 | -12 | -1.17 | faster Firefox | Page Request | 400 | 552 | 543 | -9 | -1.69 | faster Firefox | Rendering | 400 | 511 | 508 | -3 | -0.61 | ``` and the following *page-specific* results: ``` -- Grouped By page, stat -- page | stat | Count | Baseline(ms) | Current(ms) | +/- | % | Result(P<.05) ---- | ------------ | ----- | ------------ | ----------- | --- | ----- | ------------- 0 | Overall | 200 | 1122 | 1110 | -12 | -1.03 | 0 | Page Request | 200 | 552 | 544 | -8 | -1.48 | faster 0 | Rendering | 200 | 570 | 566 | -4 | -0.62 | 1 | Overall | 200 | 1005 | 992 | -13 | -1.33 | faster 1 | Page Request | 200 | 552 | 542 | -11 | -1.91 | faster 1 | Rendering | 200 | 452 | 450 | -3 | -0.61 | ``` |
