This removes the remaining references to TriangleStripDrawMode. In its place is a vertex index buffer that seems to be working. Still currently an issue with strokes made after an undo action.
Undoing a stroke and then drawing again would cause it to read old data. Now vertex/index buffers are cleared back to the prevIdx on undo/clear.
For whatever reason they still aren't rendering though.
This modifies the way indices are sent to the index buffer. If the brush is strip-based, we know verts are being sent 2 at a time. If it's stamp based, we know verts are being sent 3 at a time. SharedBufferGeometry now has a strip flag and sets indices accordingly.
These brushes were not being added to the a-drawing entity. They were also missing an undo function, which is now implemented. Rainbow brush was adjusted to use indexed BufferGeometry. Increased index buffer size for sharedbuffergeometry.
