<entry><p>Purpose: </p> </entry>
<entry><p>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. </p> <p>Default value: 64MB (<codeph>0x04000000</codeph>) </p> </entry>
