OK so if I create a shaddow framebuffer at the higher resolution, I can see it wouldn't be too difficult (but maybe inefficient) to resample it at a smaller size, but what about events like mouseover and clicks etc... how do i map these onto the original screen?
Someone feel free to jump in here and warn me in advance if you think there is no way someone with no X coding experience is going to pull this off! Especially as this needs to be all on the machine with the applications on it and the display is a fixed X display that i cannot recompile Regards Luke Reid ----- Original Message ----- From: "Mark Vojkovich" <[EMAIL PROTECTED]> To: "Luke Reid" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Sunday, November 11, 2001 12:11 AM Subject: Re: [Xpert]Intermediate X buffer > On Sun, 11 Nov 2001, Luke Reid wrote: > > > Would it be possible to have a kind of X proxy that shrinks the whole > > framebuffer?
