Title:
  [1.1.4] OpenCV assertions should be handled by SikuliX (like image
  size > region size)

Status in Sikuli:
  In Progress

Bug description:
  Sometimes I get these errors:

  org.opencv.core.CvException: CvException [org.opencv.core.CvException:
  cv::Exception: OpenCV(3.4.2) C:\build\3_4_winpack-bindings-
  win64-vc14-static\opencv\modules\imgproc\src\templmatch.cpp:1107:
  error: (-215:Assertion failed) _img.size().height <=
  _templ.size().height && _img.size().width <= _templ.size().width in
  function 'cv::matchTemplate'

  Am I right in assuming they are to do with the region being too small
  or not fitting the image/pattern I am searching for when it is found?
  I think I am able to work around by extending/recapturing the region
  after which these errors stop. But I am not 100% certain.
