Feature: Occulting

An occulting pattern (Oc) is basically the inverse of a flash. A short period of darkness with a longer period of light.

Scenario Outline: Occulting characteristic <character>

The period of a characteristic is the total time of the sequence.

A dark period is 1 second long, so the light period is one second shorter than the total period.

When I request an image with the characteristic <character>

Then the first frame is transparent for 1 second

And the next frame is <colour> for <light_period> second

Examples:

character	colour	light_period
Oc W 5	white	4
Oc R 10	red	9
Oc G 4	green	3
Oc Y 8	yellow	7
