Reading the spec, what I'm thinking of is Precise vs. Imprecise polygon mode. When rasterized in Precise mode, the pixelization will match this specification exactly. When rasterized in Imprecise mode, the pixelization may deviate from this specification by up to 1/2 pixel along any edge subject to the following constraints: ... etc. I guess you are talking about image operations though so nevermind. ;-) The Fast, Good, and Best filter aliases as you say do seem to allow pretty much any filter routine you want, at least.

I thought render gave the client the option of requesting or explicitly disabling pixel-exact rendering, according to what the client needs.

I seem to recall some discussion about this a few months ago. There are some portability issues with both getpagesize and sysconf(_SC_PAGESIZE). Because of that, XFree86 has a wrapper function called xf86getpagesize. There also seems to be a #define that aliases getpagesize to xf86getpagesize, so I'm not sure if the wrapper should be used or if getpagesize should be used. Either way, I'm sure that sysconf(_SG_PAGESIZE) should *not* be used directly. ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
patch for ia64
This patch makes the radeon driver treat ia64 as a non-legacy architecture. This patch by Alex Williamson. xc/programs/Xserver/hw/xfree86/drivers/ati/Imakefile assumes ia64 should behave the same as i386 and allows random probing or I/O port space. In moving away from the legacy model, I believe we should change this to set ATIAvoidCPIO to YES. Systems that do no provide a legacy I/O port range may otherwise machine check. --- xc-old/programs/Xserver/hw/xfree86/drivers/ati/Imakefile2003-07-25 06:04:31.0 -0500 +++ xc/programs/Xserver/hw/xfree86/drivers/ati/Imakefile2003-08-07 04:35:24.0 -0500 @@ -82,7 +82,6 @@ * ATIAvoidNonPCI necessarily implies ATIAvoidCPIO. */ #if defined(i386Architecture) || \ -defined(ia64Architecture) || \ defined(AMD64Architecture) || \ defined(AlphaArchitecture) # ifndef ATIAvoidCPIO -- Treasurer, GOLUM, Inc. http://www.golum.org ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel

Thanks to Mike Harris for this patch (slightly altered to remove RH_CUSTOM, etc). Please do not accept this Linux-specific hack of a patch; I merged it to Debian, and Mike asked me not to send it upstream. Granted, as the patch stands. However, I don't mind doing the minimal fixing up for inclusion, as this information would be extremely useful in some logs. Feel free to make it more generic and include it - that would definitely be cool. Why the extra symbol, if I may ask, instead merely using defined(linux)?
