Allow pdfium_test to send simple events to each page.
We add the --send-events flag, which causes pdfium_test to look for a .evt file with the same base name as the .pdf file being rendered, and to use its contents to drive calls to FORM_* APIs. The .evt file syntax is crude, roughly: # comments keycode,65 mousedown,right,300,300 # more comments mouseup,right,300,300 mousemove,300,300 Review URL: https://codereview.chromium.org/1898993002
