+This constant determines the maximum size of the shared heap in the font and bitmap server.
+Up to the value of the constant, the size of the virtual address range reserved for this heap
+equals the amount of physical RAM memory. As available hardware RAM sizes increase in the future,
+it may become impossible to reserve a virtual address range that big, hence the need for an upper limit.
+@note	Default value: 64MB (0x04000000)
