* Added files from http://code.opencv.org/issues/1053

The code structure had to be changed because of the
features2d/xfeatures2d split and to avoid changing
multiple modules (gaussian_pyramid doesn't seem ready
for inclusion in the (x)imgproc module).
Except for changes related to this, the patches
remain unchanged, including the outdated
copyright notice at the top of the files.

* Hide Harris-Laplace implementation behind pimpl-creating wrapper.

* Add test for Harris-Laplace feature detector.

* Handle empty images in Harris-Laplace detector.

* Replace HarrisAffineFeatureDetector with more flexible AffineFeature2D

* collapse unnecessary HarrisLaplace class into HarrisLaplaceFeatureDetector

* fold DoG pyramid code into harris_laplace_detector.cpp

* tuck auxiliary functions for Harris-Laplace into anonymous namespace

* use mask to filter keypoints in Harris-Laplace detector

* remove unused value of differentiation scale from calcAffineAdaptation

* make descriptor copy in AffineFeature2D independent of the data type

* Document interface for Harris-Laplace and AffineFeature2D

* Make type conversions explicit and decorate float literals with f in HarrisLaplace and AffineFeature2D

* Replace usage of non-standard log2 in Harris-Laplace feature detector

* Fix virtual overload errors in AffineFeature2D

* Add basic tests for AffineFeature2D and fix what they uncover

* Make type conversions in Harris-Laplace feature detector explicit

* Change license header for Harris-Laplace detector and AffineFeature2D

* Use Matx for small matrices in AffineFeature2D

* Remove redundant attributes of Elliptic_KeyPoint

* Convert Matx22f to Matx22d for inverting in AffineFeature2D

Minor documentation fixes

- dpm, freetype: fixed documentation blocks
- datasets: removed tinyXml from public interface and documentation

- changed default parameter values fr sw, sh
- switched to CommandLineParser
- added console status messages

* Correcting wrong type check in Aruco Board creation

* Double checking for CV_32FC1 and CV_32FC3 following @sovrasov's review

This patch update bioinspired opencl code to make it working
with latest opencv, major changes include:

1. data structure update, e.g. oclMat to UMat.
2. opencl kernel optimization to get it running faster
3. accuracy and perf test update.

Add MSLIC (Manifold SLIC)

* Support getTextSize() to resolve issue #927

This getTextSize() funtion helps to print more text,
either on the same line or on another line.
To add getTextSize() function, some member variables are removed
which are corresponding at putText() function's arguments.
And a negative fontHeight must be asserted.

* Fix to remove whitespace

Bug in Text module when set Optimization Level to "-Ofast" in xcode (#921)

* Bug in Text module when set Optimization Level to "-Ofast" in xcode

Bug when set Optimization Level to "-Ofast" (Fastest, Aggressive Optimizations) in xcode, read the wrong patch_size parameters to 7 (should be 8). This bug will occured in loadOCRHMMClassifierCNN function called by example_text_character_recognition and example_text_segmented_word_recognition.
