This patch goes a bit further than issue 6612 requires, and replaces all kinds of whitespace with standard spaces.
When testing this locally, it actually seemed to slightly improve two existing test-cases (`tracemonkey-text` and `taro-text`).
Fixes 6612.
This adds a checkbox with which one can disable scrolling, for example to look back at output during testing. Note that the styles are inline because the test runner removes all <style> elements for each test.
- Improve variable names and move variables to the top of the method
- Use constants where possible
- Only print the delay text if there is an atual delay set
- Simplify continuation logic in _nextTask
- Do not pass anything to clearCanvas: we can get the context from this.canvas there.
- Remove innerHTML and replace it with textContent. Add a comment why insertAdjancentHTML is so important for performance and runtime.
- Merge _quit and _sendQuitRequest.
- Extract NullTextLayerBuilder and SimpleTextLayerBuilder from the driver code and create classes for them.
- Move options to the constructor and pass in HTML elements instead of getting them in the driver.
- Remove unused masterMode variable.
- Minor method name updates.
The rest is only moving/indenting existing code and adding 'this'.
- Remove a hack for Chrome on Windows because we do not run Chrome on the Windows bot anymore, so it added unneeded complexity.
- Merge nextTask and continueNextTask functions. nextTask did nothing more than calling cleanup. This change also allows us to remove the callback for that function.
- Remove unnecessary one-line functions.
