    30 This constant determines the maximum size of the shared heap in the font and bitmap server.

    31 Up to the value of the constant, the size of the virtual address range reserved for this heap

    32 equals the amount of physical RAM memory. As available hardware RAM sizes increase in the future,

    33 it may become impossible to reserve a virtual address range that big, hence the need for an upper limit.

    42 This constant modifies the writable data paging mode used by the font and bitmap server.

    43 It is configured at rom build time via the following definitions in fbserv.iby:

    44 	SYMBIAN_GRAPHICS_FBSERV_PAGEDATA

    45 	SYMBIAN_GRAPHICS_FBSERV_UNPAGEDDATA

    46 	SYMBIAN_GRAPHICS_FBSERV_PAGE_BITMAP_DATA_ONLY

    47 	SYMBIAN_GRAPHICS_FBSERV_PAGE_BITMAP_DATA_AND_SHARED_HEAP_ONLY
