Subdivided the new icons in 3 size categories. As requested by UX
Used the company naming scheme for uniformity and easy recognition.
Known issues:
- Top/Bottom category wasn't taken into account by UX at the time. Since
this is a recent addition. Both the Walls and Top/Bottom will be updated.
- Cloud/Network connection icons 12px don't render correctly. Due to the
theme-ing.
- Extruder Icons do not render correctly.
CURA-8010_new_icons
This is the first draft of the Support Eraser tool. The plugin creates a cube mesh which has the `anti_overhang_mesh` decorator causing it to block the creation of support material for overhangs within its volume. This distinction is necessary to avoid confusing this behavior from actually erasing a _portion_ of a support structure.
Some (non-necessary) improvements could be made such as:
- Better graphical style
- Discussion of whether the cube should be able to pass through the build plate or not
- Possible improvements to the tool's icon
- Placing the cube at a cursor click location
