* added color support to stroking and non stroking color spaces
* extended LTCurve, LTLine and LTRect to save painting information
* modified PDFLayoutAnalyzer to populate the shapes with painting information
* Removing all the "#!/usr/bin/env python" lines, they do not need for python3, solving issue number: #19.
* Restored all the shebangs in the tools and tests folders (because they are real executables) but used "#!/usr/bin/env python" instead of "#!/usr/bin/python" as this blog points out: https://www.peterbe.com/plog/importance-of-env
Removed also the shebang from pdfminer/psparser.py file.
This commit finds horizontal neighbors in a horizonal line and merges them together into a single horizontal line if necessary. This leads to much better text extraction if the PDF was created in a funky way.
For example (test case coming), I have seen PDFs which are written almost like vertical columns, but the text is entirely horizontal.
1.
When detecting text in a horizontal line, we already add a space between words if separated by more than word_margin apart. However now, we only do it if there is not already an existing space. This prevents multiple spaces being placed between words.
2.
Detect a horizontal line if the line is zero width. This improves our detection of horizonal lines when looking for both horizontal and vertical.
3.
Don't detect a vertical line if the previous letter is whitspace. Prevents double spaces being caught as vert lines.
4.
Improve upon an unfortunate O(N^2) algorithm which I have seen taking many minutes to execute. Unfortunately, while the "fix" reduces algorithmic complexity, it isn't technically correct, so we only do it when we know things will take a long time.
