This allows for typing [8] instead of [8, 8, 8, 8] to specify the same margin on all edges, for example. The constructors follow CSS' style of specifying margins. The added constructors are: - Margins(int all): Sets the same margin on all edges. - Margins(int vertical, int horizontal): Sets the first argument to top and bottom margins, and the second argument to left and right margins. - Margins(int top, int vertical, int bottom): Sets the first argument to the top margin, the second argument to the left and right margins, and the third argument to the bottom margin.
