Defines a flexible gridarea that consists of columns and rows.
定义由行和列组成的灵活的网格区域。

We calibrate system measure coordinates of every gridarea according to the linearity equation.
以此直线方程校正网格区间内的系统测量坐标。

A conclusion to this is when designing a grid, subdivide so there is a fractional relationship to the whole gridarea, eg, 1/3 3/4 2/3 etc. but more importantly be consistent.
