Add option to show result at beginning for recorder export
Add a "Show result on first frame for" option to the recorder docker exporter. This option copies the last frame to the beginning and extends it the duration specified.
Specifying 0 seconds adds no frames to the beginning of the video. Defaults to 2 seconds.
This was originally requested on Krita Artists
- Set the "show result on first frame" option to some duration ( example: 5 seconds) and export video
- Set the "show result on first frame" to 0 and confirm no extra frames are added to the beginning of the video
I confirmed this builds.
I confirmed Krita ran and the relevant functions work.
I tested the relevant unit tests and can confirm they are not broken. (If not possible, don't hesitate to ask for help!)
I made sure my commits build individually and have good descriptions as per KDE guidelines.
I made sure my code conforms to the standards set in the HACKING file.
I can confirm the code is licensed and attributed appropriately, and that unattributed code is mine, as per KDE Licensing Policy.
