You had some patches a while ago that did CMS -> UMS conversion, but<br>
ended up not being needed -- if we wanted ot resurrect the conversion<br>
code itself, it would now be straightforward to get CMS for signed<br>
integer surfaces as well, until we see the app try to mask off<br>
channels.<br>
<br>
Do you think this is worthwhile?<br></blockquote><div><br></div><div>For now, I don't think it's worthwhile. My guess is that real-world apps using signed integer multisample surfaces are very rare (perhaps non-existent), so I'd prefer not to resurrect that hack until we find an app that needs it.<br>
