Flag indicating whether the library has been initialized with multicolor tile support.

 extern mr_boolean MR_MULTICOLOR;

Flag indicating whether the library has been initialized with multicolor tile support or not. It can be used to differentiate the software dynamically, depending on the graphic possibilities. This flag is initialized to mr_false where the program initializes the library with the call to mr_init(). However,if the mr_init_multicolor() function is called, this flag is set to mr_true.

Note that the library already takes into account the difference between the two modes, and transparently converts multicolored tiles into single-colored tiles. The vice versa obviously makes no sense.
