introducing a tutorial for the retina model
adding retina tutorial
updated tutorial, need spell check, validation, nicer images and a discussion on parameters
updated tutorial, rapid spell check, retina parameters discussion added
added retina code tutorial
updated first image sample
minor update
minor updates for doc redirections and tutorial images size
Added float, uint64, and uchar params to Algorithm
Made changes to work in cv::Algorithm with parameters of these types.
Also fixed SimpleBlobDetector -- now it can be created by
cv::Algorithm::create and it can work with cv::Algorithm::set/get.
Try to fix Mac compilation issue.
The next attempt to fix a build error on Mac.
alpha channels support for 8-bit tiffs
added test for 4 channel tiff
* img_test is now tested for channel numbers instead of img
* fixed indentation to use spaces and trailing spaces
API of TiffDecoder back to what it was - normalizeChannelsNumber moved to protected
test code unified - channels number is tested for other formats as well
fixed tab indent
Added two kernels to existing SVM framework
Histogram intersection kernel (accessible by using SVM::INTER in CV namespace as kernel_type)
Exponetial chi2 kernel (accessible by using SVM::CHI2 in CV namespace as kernel_type)

Formulars:
Exp-CHI2
k(x,y) = exp(-gamma * CHI2(x,y))
CHI2(x,y) = 1- 2* SUM_i[(xi-yi)²/(xi+yi)]

Intersec
k(x,y) = SUM_i[min(xi,yi)]
Changed line 1266 in svm.cpp to allow the new kernels to be used
updated OpenGL functionality:

* removed OpenGLFuncTab, now extensions are loaded internally
* added support of GlBuffer and GlTexture2D to InputArray/OutputArray
* added ELEMENT_ARRAY_BUFFER and PIXEL_PACK_BUFFER targets
* added copyFrom/copyTo method for GlBuffer and GlTexture2D
* removed GlFont
* removed pointCloudShow
* removed OpenGLCleanCallback
* added Access parameter to GlBuffer::mapHost
* added autoRelease parameter to all create methods
Tutorial for ARM Linux cross compilation added.
