The algorithm for cutting squares out of a given bitmap is such that the picture is perfectly reproduced when a bitmap the size of the complete board is given. +If the filename ends in "-NxM.png", with integer N and M, +it is assumed to contain a bitmap of a complete board of N files +and M ranks, and XBoard will scale it to exactly match the +current square size. +If N=M=0 it scales the entire bitmap to the size of the board, +irrespective of the number of files and ranks of the latter. +Without any -NxM suffix textures are only blown up by an integer +factor when they are smaller than the square size, or, +when the name starts with "xq", too small to cover the +complete Xiangqi board.
