* Track runes in IdentityEncoder (for subsetting), track decoded runes
* Working with the identity encoder in font_composite.go
* Add GetFilterArray to multi encoder. Add comments.
* Add NewFromContents constructor to extractor only requiring contents and resources
* golint fixes
* Optimizer compress streams - improved detection of raw streams
* Optimize - CleanContentStream optimizer that removes redundant operands
* WIP Optimize - clean fonts
Will support both font file reduction and subsetting. (WIP)
* Optimize - image processing - try combined DCT and Flate
* Update options.go
* Update optimizer.go
* Create utils.go for optimize with common methods needed for optimization
* Optimizer - add font subsetting method
Covers XObject Forms, annotaitons etc. Uses extractor package to extract text marks covering what fonts and glyphs are used. Package truetype used for subsetting.
* Add some comments
* Fix cmap parsing rune conversion
* Error checking for extractor. Add some comments.
* Update Jenkinsfile
* Update modules
* Fixed issue #243. Added optimize integration tests.
* Minor style change.
* XObjImage getParamsDict updates Columns and Rows.
* Added doc file for the optimize/tests package.
* UpdateParams for CCITTFax Encoder accepts Width and Height also. Removed
GetParamsDict Columns and Rows parameters from model.Image and
model.XObjImage.
* Fix i386 issue for the jbig2 arithmetic encoder.
* Added 386 architecture to the .travis/cross_build.sh
