Detailed Description

A computed expression in our simple vector drawing language.

While it appears to take the form of a tree, this is actually merely a list; concerns such as precedence of operators are currently recomputed on every recalculation.

Created by meta_draw_spec_new(), destroyed by meta_draw_spec_free(). pos_eval() fills this with ...FIXME. Are tokens a tree or a list?
