2017-12-05Avoid integer overflows in CPDF_FixedMatrix::Transform().Lei Zhang
Use floating point math and saturated_cast to calculate the transform. Refactor CFX_BilinearMatrix::Transform() to share common code, instead of using integer math and CheckedNumerics.

2017-11-30Rewrite lower level details of extracting text from pageRyan Harrison
The current implementation of text extraction was difficult to understand, duplicated logic that existed in other methods, and wasn't clear about the units the inputs were in. It also didn't handle control characters correctly. The new implementation leans on the methods for converting indices between the text buffer index and character list index spaces to avoid duplication of code. It also makes it clear to the reader that inputs are in the character list index space. Finally, it fixes issues being seen in Chrome with respect of ranges being slightly off. This CL also adds a test for extracting text that has control characters.
