The only user of the geometry coordinates is the software sprite code,
which uses them to remove the pointer whenever the window beneath is
being used as a source. However, using Window pictures as a source is
extremely rare (let alone *partial* windows), so there is no harm done
in just validating all of the drawable.
Additionally, the miSourceValidate() function was buggy in at least
three respects:
(a) It added drawable->{x,y} before calling down, which is wrong since
the misprite code already adds them in its check. (Alternatively,
the misprite code is wrong, but there are actual users who would
notice if that code was broken).
(b) It didn't account for the width of the interpolation filter, so if
the Picture had a bilinear or convolution filter, the edges
surrounding the source area would not be validated.
(c) It didn't validate alpha maps.
Finally, computing the bounding box of the transform on every
composite request was a real performance issue in pixman, so
presumably it could be one here as well.
This patch changes miSourceValidate() to simply validate all of the
underlying drawable.

This patch fixes two bugs:
size is calculated as glyph height * padded_width. If the client submits
garbage, this may get above INT_MAX, resulting in a negative size if size is
unsigned. The sanity checks don't trigger for negative sizes and the server
goes and writes into random memory locations.
If the client submits glyphs with a width or height 0, the destination
pixmap is NULL, causing a null-pointer dereference. Since there's nothing to
composite if the width/height is 0, we might as well skip the whole thing
anyway.
Tested with Xvfb, Xephyr and Xorg.

dixLookupResource attempted to automatically detect whether the caller

RT_NONE. Instead of trying to make the guess better, this patch just reverts
the unification and creates separate functions for each operation.
A grep on xorg/* revealed there's no consumer of this define.
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."

All .a libraries were converted to .la, and instead of linking the
Xorg binary with a mix of .a and .la, and adding some libraries more
then once in the command line, etc, now it generates a single libxorg.la
from all the required convenience libraries, and links with a dummy
xorg.c (that should usually be the file with the main function...).
This removes the requirement of some things like libosandcommon and
libinit, that existed to circumvent problems when linking multiple
.a and .la in the final Xorg binary.
The "symbol table" is now generated dynamically, by a shell script,
with an embedded gawk parser that parses cpp output. The new file
sdksyms.sh is generated by hand by analyzing all Makefile.am's and
making it create a sdksyms.c file, that includes all sdk headers that
will add symbols for the Xorg binary. Module headers aren't read, and
a in 2 files it was required to add a "<hash>ifndef XorgLoader" around
declarations shared between the Xorg binary and libextmod. A few
other changes were added to other sdk headers, like preventing
multiple inclusion, or including other headers to satisfy dependencies.
This should be a lot more portable, and better (hopefully properly)
using libtool to generate convenience libraries.
Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.
This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)
LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.
xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).
These symbols were removed from the X Server, or never declared.
One symbol that may need special attention is XkbBuildCoreState(),
that doesn't have a prototype anywhere, but is called from
xkb/xkbEvents.c:XkbFilterEvents(), and also used by the macros
XkbStateFieldFromRec() and XkbGrabStateFromRec() defined in
include/xkbstr.h.
fb/wfbrename.h also may need some cleanup, as it makes several
"renames" of non existing symbols.
This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.
Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.

Signed-off-by: Keith Packard <keithp@keithp.com>
PictureTransformPoint computes homogeneous coordinates internally, but fails
to handle intermediate values larger than 16.16. Use 64 bit intermediate
values while computing the final result at 16.16 and only complain if that
result is too large.
PictureTransformIsIdentity was completely wrong -- it was not checking for
identity transforms at all.
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.
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...
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.
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.
Integer overflows can occur in the code validating the parameters for
the SProcRenderCreateLinearGradient, SProcRenderCreateRadialGradient
and SProcRenderCreateConicalGradient functions, leading to memory
corruption by swapping bytes outside of the intended request
parameters.
An integer overflow may occur in the computation of the size of the
glyph to be allocated by the ProcRenderCreateCursor() function which
will cause less memory to be allocated than expected, leading later to
dereferencing un-mapped memory, causing a crash of the X server.
An integer overflow may occur in the computation of the size of the
glyph to be allocated by the AllocateGlyph() function which will cause
less memory to be allocated than expected, leading to later heap
overflow.

These hints allow an acceleration architecture to optimize allocation of certain
types of pixmaps, such as pixmaps that will serve as backing pixmaps for
redirected windows.
over to new system.
Need to update documentation and address some remaining vestiges of
old system such as CursorRec structure, fb "offman" structure, and
FontRec privates.
The plural version is now static, which is fine since it was only ever called
from within picture post-init anyway. The body of the work is now done with
a one-shot (public) function that operates on a single format at a time.
The pixman headers have been located under pixman-1/ instead of pixman/ since
around 2007-08-06, and pixman-1.pc has the updated include paths to account
for this.
This reverts commit feb1b3e455.
