Quote Alan Coopersmith: "The consumer was in past versions of the headers now located in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h, all the event definitions were only available if NEED_EVENTS were defined, and all the reply definitions required NEED_REPLIES. Looks like Xproto.h dropped them by X11R6.3, which didn't have the #ifdef's anymore, so these are truly ancient now."

RandR matrix computations lose too much precision in fixed point; computations using the inverted matrix can be as much as 10 pixels off. Convert them to double precision values and pass those around. These API changes are fairly heavyweight; the official Render interface remains fixed point, so the fixed point matrix comes along for the ride everywhere. commit 97ab0c6eff870b52c0383b63a78cec49059b2545 Author: Keith Packard <keithp@keithp.com> Date: Tue Mar 18 15:15:40 2008 -0700 When converting from double to fixed, round carefully. This reduces the matrix representation error after inverting a transformation matrix (although it doesn't eliminate it entirely). Perhaps we should extend Render to include 64-bit floating point transforms... commit 160252d94f04acc95f0a4e0f884ff565a5aa0744 Author: Keith Packard <keithp@keithp.com> Date: Mon Mar 17 23:03:56 2008 -0700 Add matrix inversion function (uses doubles) The obvious matrix inversion function, coded using doubles to avoid fiddling with fixed point precision adventures. commit ff9d1cd843a9b0aba69a3d788b21d5f6af702590 Author: Keith Packard <keithp@keithp.com> Date: Thu Mar 13 21:30:18 2008 -0700 Add funcs to convert between protocol and pixman matrices commit f547650328287545a7a4d96df8d6a6c606dd95a9 Author: Keith Packard <keithp@keithp.com> Date: Thu Mar 13 14:50:13 2008 -0700 Export a bunch of matrix operations from render. The render extension uses many matrix operations internally, this change exposes those functions to other parts of the server, drivers and extensions. The change is motivated by the 'transform' additions to the RandR extension but will likely be useful elsewhere. Backport to nx-libs: Mike Gabriel <mike.gabriel@das-netzwerkteam.de>

To prepare for RandR using filters in transforms, split out code paths so that the RandR code can validate the filter name and parameters during the transform set operation so that use of the filter later will not have unreportable errors.

* Move each screen's root-window pointer into ScreenRec.Mike Gabriel2016-06-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Backported from X.org: commit e7fae9ecc42ab5e73b89117722dbf4117d928f9a Author: Jamey Sharp <jamey@minilop.net> Date: Sat May 22 00:26:28 2010 -0700 Move each screen's root-window pointer into ScreenRec. Many references to the WindowTable array already had the corresponding screen pointer handy, which meant they usually looked like "WindowTable[pScreen->myNum]". Adding a field to ScreenRec instead of keeping this information in a parallel array simplifies those expressions, and eliminates a MAXSCREENS-sized array. Since dix uses this data, a screen private entry isn't appropriate. xf86-video-dummy currently uses WindowTable, so it needs to be updated to reflect this change.

| | | | | | | | | | | | | | | | | | | | | This is a huge mechanical patch and a few small fixups required to finish the job. They were reviewed separately, but because the server does not build without both pieces, I've merged them together at this time. The mechanical changes were performed by running the included 'fix-region' script over the whole nx-X11/programs/Xserver tree: $ cd nx-X11/programs/Xserver && ( git ls-files | grep -v '^fix-' | xargs ./fix-region; ) And then, the white space errors in the resulting patch were fixed using the provided fix-patch-whitespace script. $ sh ./fix-patch-whitespace Thanks to Jamey Sharp for the mighty fine sed-generating sed script. v1: Keith Packard <keithp@keithp.com> (X.Org xserver commit: 2dc138922b7588515d5f2447e4b9dcdc0bef15e0) v2: Mike Gabriel <mike.gabriel@das-netzwerkteam.de> (apply fix-region script to nx-libs)
* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-283-8/+8
| | | | | | | | | | | | | | | | | | | | In the process of building nxagent against more and more system-wide installed X.org libraries, we come to the limit of including structs from this (bundled nx-X11) and that (system-wide X.Org) library. This commit introduces a clear namespace separation of headers provided by nx-X11 and headers provided by X.Org. This approach is only temporary as we want to drop all nx-X11 bundled libraries from nx-libs. However, for a while we need to make this separation clear and also ship some reduced fake X.Org headers that avoid pulling in libX* and libNX_X* symbols at the same time. This patch has been tested on Debian jessie and unstable and requires no overall testing on various distros and distro versions, as we finally will drop all libNX_X* libraries and build against X.org's client libs. For now, this hack eases our development / cleanup process.
