Use FPDFText_GetBoundedText() to get the visible text in a test.

Add a test PDF with multiple pages, each with a different media box and
crop box. Demonstrate how FPDFText_GetText() gets all the text on the
page, and how FPDFText_GetBoundedText() with the right bounding boxes
gets only the visible text on the page.

Also fix a small nit in CPDF_TextPage::GetTextByRect() found while
writing this CL.
