- After posting this, I had re-grepped the release notes for X11R5. It says
- there, (page 24 in the text form):
-
- - oclock
- -
- - Oclock has a new -transparent option.
-
- and later on page 34 (section 11.7, PEX, 11.7.1, Standards and Functionality):
-
- - Functionality not completed in this release is as follows: [note the negative]
- .....
- - In the Server:
- -
- - Backface Attributes and Distinguish Flag
- - Font sharing between clients
- - Patterns, Hatches and associated attributes
- - Color Interpolation
- - Transparency
- - Depth Cueing for Markers
- - Z-buffering
- - Double Buffering
-
- In the source tree there is some mentioning of transparent attributes in
- various server codes, and lots in oclock.
-
- In other words, they thought about transparency and demonstrated it with
- oclock at application level, but not a lot is in there yet.
-
- Serves me right for skimming release notes rather than reading them, and then
- quoting from memory 16 months later ...
-
- But just to have a dig: Since SGI has already solved transparency at GL level,
- would it not be a nice idea for them to put it into their X server and
- contribute the code to MIT ?
