Mesa.patches: Disable 4001_Fix-non-working-GLX-in-64bit-Xorg-7.0.patch. It patches a file, we don't build and that we remove in roll-tarball.sh.

roll-tarballs.sh: Remove even more files from nx-X11/extras/Mesa/. This roll-tarball.sh version has been used for generating the 3.5.99.8 tarball.

nxcomp: Set TokenSize to 1536 for link type ADSL and WAN. Improving non-xrender based  browser scrolling behaviour when link type is set to ADSL or WAN.

 In the 40-ies (talking about release version numbers), Firefox started
 using the Skia library [1] for client-side rendering of browser content.

 With current versions of Firefox you can switch between libXrender based
 rendering (esp. of Fonts) and Skia based rendering:

    gfx.xrender.enabled = true|false

 Some time around Firefox 52, the default for the gfx.xrender.enabled
 setting got changed by Firefox upstream from true to false. So nowadays,
 Firefox uses Skia by default.

 However, it turns out that Skia scales really badly on remote X11
 connections. Scrolling of long web pages becomes really jolty.

 Something similar could be observed earlier already when using
 Chrome or Chromium (which also has been using Skia for some time
 now).

 This change in nxcomp works around those issues and greatly
 improves scrolling and general browser experience on medium
 throughput networks (like cable modem, ADSL, HDSPA, slow LTE).

 In nxagent sessions, all X11 clients have a representation of their NX
 session-side window object on the real X-Server side.

 The window object gets stored in the new NX_REAL_WINDOW window property
 immediately after window creation. This mapping is created in
 nxagentCreateWindow().

 On session resumption, the client side window IDs normally change. Thus,
 during session resumption, all NX_REAL_WINDOW properties require being
 updated. This happens in nxagentReconnectWindow().

 While a session is suspended, the NX_REAL_WINDOW property does not
 exist. It gets removed during nxagentDisconnectWindow().

hw/nxagnet/Atoms.c: In DEBUG mode, we need validateString() which is not statically defined in Utils.h. Thus including it for DEBUG builds.

Fix FTBFS on Linux based HP-PARisc 32-bit systems. Thanks to John Paul Adrian Glaubitz from FU Berlin for providing access to a corresponding porters' machine.

 This partially reverts nx-libs commit f6dcf2fe. The 'hpux' stuff stays
 out, the __hppa__ gets re-introduced.

    dix: Fix image byte order on big endian hardware

    Make sure X_BIG_ENDIAN/X_LITTLE_ENDIAN are defined before actually using
    them.

    Otherwise, image byte order could be wrong on big endian hardware even
    though endianess detection is correct.

    dix: Remove arch awareness from servermd.h (v2)

    At this point we have no architectures where image byte order is
    different from bitmap bit order, or where either of those two are not
    also the native word endianness.  Hooray, one more place where we don't
    have to worry about enabling new CPU architectures.

    v2: Rebase to master to handle the addition of ppc64le, arc, and xtensa,
    and use autoconf's endianness detection instead of gcc predefines.
