// Changes contributed by Bernie Bright <bbright@c031.aone.net.au>
|
|
// - The new classes in libmisc.tgz define a stream interface into zlib.
|
|
// I've put these in a new directory, Lib/Misc. Feel free to rename it
|
|
// to something more appropriate. However you'll have to change the
|
|
// include directives in all the other files. Additionally you'll have
|
|
// add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
|
|
//
|
|
// The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
|
|
// test so I've included the required changes in config.tgz.
|
|
//
|
|
// There are a fair few changes to Simulator/Objects as I've moved
|
|
// things around. Loading tiles is quicker but thats not where the delay
|
|
// is. Tile loading takes a few tenths of a second per file on a P200
|
|
// but it seems to be the post-processing that leads to a noticeable
|
|
// blip in framerate. I suppose its time to start profiling to see where
|
|
// the delays are.
|
|
//
|
|
// I've included a brief description of each archives contents.

// Taken from zlib-1.1.3/contrib/iostream/.
