HiDPI text rendering support for time series chart editor
Related to #152 (closed), currently none of the text rendering done in the time series chart editor takes into account display zoom (DPI) setting.
The texts at the following locations need to be considered:
- x and y-axis tick texts
- Chart hairline value tooltip texts (this should be the simplest to fix)
- Auto On/Off, Auto-scroll on/off texts at the ends of axes
