Most notably the interfering options tracked in #398, but also made "Center viewport on model" and "Zoom in on model" automatically deselect and de-apply if viewport gets manipulated by user, therefore properly allowing the re-select by the user to work to.
Closes#398
- Refactored drawGrid into two functions drawRectangularGrid and drawCircularGrid
- Made sure grid for circular beds always "starts" at (0,0) so that e.g. for a radius of 105mm the center of the bed will be on the grid lines
- Made center on circular bed be better visible by making origin lines thicker
- Made initial focus on bed center properly
- confirmation dialog when trying to visualize large files (different threshold for mobile and "regular" devices, configurable of course, although only via config file right now) - should also help a bit with issues leading to #215
- proper clearing of the viewer area when reconnecting to the backend (e.g. after server restart)
Also all of this plus previous commits closes#35
- GCODE viewer now supports multiple extruders and configurable bed sizes
- GCODE viewer also now based on callbacks and config injection instead of dependence on elements in the embedding website
- Switched GCODE viewer to bootstrap-slider for the layer/command sliders, patched bootstrap-slider a bit up (TODO: PR to upstream)
- GCODE interpreter in backend also calculates filament usage for all extruders
- More consequent use of LESS, switched bootstrap to LESS source to have access to variables and mixins, introduced config setting to switch between usage of compiled CSS (checked in as well) or LESS, defaults to CSS
