Added three more selection markers (plus, rhombus, and square shapes), and applied the plus (+) shaped selection marker to the healer, to distinguish it from other units, and to fit its aura range.
The images are my own work; I hereby release them under CC BY-SA 3.0.
For comparison, heroes (star) and champions (arrow) also have different selection markers (unchanged).
Update:
- Two more selection marker shapes: {8/2} octagram, hash
- Added new chevron icons for ranks 0 to 12
None of these new images is used, however, they are potential useful in the future or for mods.
Also considered many other selection marker shapes, but rejected them either because they're too similar and approach the circle (e.g. {5/1} pentagon, {6/1} hexagon, {7/1} heptagon, {8/1} octagon, etc), or because they are beyond my limited drawing skills (e.g. regular {12/5} dodecagram; narrow, wide, and regular {8/3} octagrams; regular {3/1} triangle; etc.).
