Christian Duerr ac93f6d031 Truncate invisible lines before storing ref-tests ... Because there is no good way to store invisible lines in a backwards- and forwards-compatible way, they buffer now gets truncated before dumping the state of a grid when creating a ref-test. This involved a few workaround of which a few required adding additional methods which are only used in ref-tests, these should be minimal though. Since this required the creation of a truncation method anyways, some logic has been added which automatically truncates the invisible buffer when there are more than X (set to 100) invisible lines. This should not impact performance because it rarely occurs, but it could save a bit of memory when the history size is shrunk during runtime (see #1293). This also adds an optional `config.json` file to the ref-test output where it is possible to manually specify variables which should override config defaults, this has been used only for history_size so far. Creating a new ref-test does also still work, so there was no regression here, if history size is altered, the config.json just has to be created manually with the content `{"history_size":HIST_SIZE}`, where `HIST_SIZE` is the desired history size.		2018-06-02 09:56:50 -07:00
