Consistent with the test made in cv::boxFilter, it adjusts the kernel size to the source size only if the border is not BORDER_CONSTANT and if BORDER_ISOLATED is set. Otherwise, the source has to be considered possibly in a larger image (i.e. the source being a ROI) in witch the kernel should apply.

removed invalid condition, it is always false

add missing stream parameter to call_resize_linear_glob

Ticket 3458 (http://code.opencv.org/issues/3458)

version of print_params for backwards compatibility.

CvCapture_GStreamer::retrieveFrame assumes that RGB videos are 24BPP.
This is not necesarily the case, unless we explicitly tell GStreamer
that we want 24BPP RGB streams.

Adding bpp=(int)24 to the appsink caps.
