Some tricks as workaround for the terrible huge pdf files

[kkocdko]

I usually use pdf.js as my local PDF books viewer because it's more convenient to view in browser tabs instead of another standalone window. Hovever the Chromium's PDF implement seem sucks for huge files so here some hacky tips with implement:

• Some files have accurate transparent text layer. You can hack the showText() and modify text layer to visable, to improve the performance a lot.
• Or disable the text layer also have some effects.
• Huge size, pics were not compressed enough. The Chromium's always load whole file into memory, we can use disableAutoFetch: true, disableStream: true in pdf.js to prevent this.

(yeah I knew that these files were also sucks because their maker, pirated of course, didn't care about optimization)
