Visualize group resource counts

[sourencho]

Description

Show one cell per resource in group. Meaning if you have one blue and one red resource, half the group will be blue and the other half red. With three blue and one read, roughly three quarters of the group will be blue and the one quarter red. A property of displaying group resources this way is that if you see a group that's just read, there is no way to know if it has one red or a hundred - but the moment it gathers one other resource it becomes apparent.

[c209825] Visualize group resource count via voronoi shader

• The shader voronoi_counts.frag colors cells according to resource amounts passed in
• Groups need to have a max resource count for the shader to know how many cells to draw.
• If the number of resources or their colors change, the shader code will need to be updated manually.

[b80d744] Show ratio of resources in mine

• Rather than having a set of cells that get filled with colors as you collect resources, have as many cells as resources collected and convey the resource amounts relative to one another. Meaning if you have one blue and one red, half the group will be blue and the other half red. With three blue and one read, roughly three quarters of the group will be blue and the one quarter red. This way we don't need to do know the "max" amount of resources a group can hold since the cell number grows as the resource count grows. A property of displaying it this way is that if you see a group that's just read, there is no way to know if it has one red or a hundred - but the moment it gathers one other resource it becomes apparent.
