For semantic segmentation tasks eraser size is static but should be adjustable

[royschwartz2]

Is your feature request related to a problem? Please describe.
The current eraser size for semantic segmentation tasks is static and cannot be changed. For tasks requiring pixel-accuracy it's too big.

Describe the solution you'd like
The brush slider should also work for the eraser. Instead, when moving the slider the brush tool is selected again.

Describe alternatives you've considered
