7c5e286834 video_pattern_generator: catch errors + init noexcept 
The out of bound access in previous commit was silently suppressed
because the exception was passed and catch(...) didn't print anything.

- init is now noexcept
- while still letting catch(...) without err msg, because when int is
  thrown, it is expected that thrower has already printed a cause (or
  help), catch std::exception

a541bcddf5 image_pattern_generator: fixed EBU/SMPTE patters 
- EBU didn't work at all (out of bounds access)
- last column of SMPTE pattern has full luminance but should have .75%

481cc66821 video_pattern_generator: log "Fill rect" as debug 
+ use logger where there hasn't been

The messages are not particulary useful and produce higher number of
lines on init so it would be better to use debug level.

cd51c3b831 testcard gray pattern: decrease default step to 1 
The previous value 16 was too much fast (one iteration lasted only 16
frames) which was even unsuitable for latency evaluation for higher
latency compressions.

With the value 1, the latency can be directy read from difference of
luma on subsequent lines.

7737a4f878 replace some color_out macros with stream-oriented 
For ostreams, the stream macros are prefered both over raw escape
sequence macros (guarantee style/color termination) and function-like
ones in form T<PROP>(), because it allows also different argument than
C string literal.

innocent ones (performance) and not new (detected because of new release
of Coverity).

b9ea5ec9a9 testcard: encapsulate frame sequence to video_pattern_generator 
Get every frame from video_pattern_generator, i. e. every frame, not
only first one.

This will allow more complex pattern than just sliding over one picture.

a0458aa6dd video pattern generator: finished SMPTE bars 
It is not fully-conformant but the wiki description is rather vague and
it is eg. inpossible to represent a "superblack" color if we assume 0 as
a base black.

e4f56be955 prevent dangling lambdas 
Prevent dangling parameter-less lambdas. Although it may not be so dangerous
(operator() should be a plain function in the end), it is not correct.

different data - mention this in help + todo.

out-of-range YUV values.
