How do I change the default depth or visual class in OpenWindows?
In the past, OpenWindows would always use 8 bit PseudoColor as the default visual, even when a 24 bit frame buffer is being used. However this rule is now changing. Starting with the S24, OpenWindows will default to 24 bit TrueColor. This rule is expected to continue as new graphics products are developed, however 8 bit PseudoColor will remain the default visual for the existing 24 bit frame buffers, such as the SX, ZX, GT and GS. A 24-bit TrueColor default reduces colormap flashing. DeskSet and other applications that are really visual-independent then don’t take up entries in the colormap. Thus those applications that do care have more available. It is expected that most applications will be able to use 24-bit TrueColor. Fewer and fewer people should have to play colormap tricks such as 4/4 double buffering or wierd plane masking as screen update rates go up. Also, the data copy advantage of 8-bit pixels is going away with SX, S24 and future Frame Buffers.
