I don't know why _cairo_boilerplate_xlib_window_create_surface()
is in the Render-only section of the code, but since it is, this
patch makes the boilerplate at least compile if we don't have
Render support built in.
I updated the Free Software Foundation address using the following script.
for i in $(git grep Temple | cut -d: -f1 )
do
sed -e 's/59 Temple Place[, -]* Suite 330, Boston, MA *02111-1307[, ]* USA/51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA/' -i "$i"
done

cairo_boilerplate_xlib_surface_disable_render() is not defined when
compiling without XRender, but it was used nonetheless. Replace it
with an empty stub when XRender is not available.
The new xcb surface uses xcb_writev() and xcb_take_socket()
which were introduced in libxcb 1.1.92. The boilerplate
in turn uses the major_code and minor_code fields in
xcb_generic_error_t, which were introduced in 1.4.
We were exposing the actual value of CAIRO_FORMAT_INVALID
through API functions already, so it makes sense to just
go ahead and put it in the cairo_format_t enum.
cairo_gl_surface_create_for_window assumes CONTENT_COLOR_ALPHA, so
make sure the fbconfig we choose is good enough. Fixes gl-window
testcase results to basically match the non-window testcases.
Trying to build xcb on a system without SHM wrapped by xcb. The right
answer would be to build libxcb-shm. The quick answer is to compile out
shm support.
Still an experimental backend, it's now a little too late to stabilise
for 1.10, but this should represent a major step forward in its feature
set and an attempt to catch up with all the bug fixes that have been
performed on xlib. Notably not tested yet (and expected to be broken)
are mixed-endian connections and low bitdepth servers (the dithering
support has not been copied over for instance). However, it seems robust
enough for daily use...
Of particular note in this update is that the xcb surface is now capable
of subverting the xlib surface through the ./configure --enable-xlib-xcb
option. This replaces the xlib surface with a proxy that forwards all
operations to an equivalent xcb surface whilst preserving the cairo-xlib
API that is required for compatibility with the existing applications,
for instance GTK+ and Mozilla. Also you can experiment with enabling a
DRM bypass, though you need to be extremely foolhardy to do so.
As proof-of-principle add the nearly working demonstrations of using DRM
to render directly with the GPU bypassing both RENDER and GL for
performance whilst preserving high quality rendering.
The basis behind developing these chip specific backends is that this is
the idealised interface that we desire for this chips, and so a target
for cairo-gl as we continue to develop both it and our GL stack.
Note that this backends do not yet fully pass the test suite, so only
use if you are brave and willing to help develop them further.
Add a gl-window boilerplate target to exercise using GL to render to a
visible Drawable -- for instance, a window has a different coordinate
system to a framebuffer...
We were using _GNU_SOURCE throughout the codebase, so simply define it
once during configure. This is the easiest method to enable recursive
mutexes using pthreads, as required in a pending patch.
XCB avoids the dreaded abort on XError mechanism by forcing the client
to perform deferred error checking. So do so. This allows us to combine
the fire-and-forget rendering model with accurate error checking,
without killing the client or mixing our errors with theirs.
XCB for the win!
This appears to be the simplest mechanism to build libglew at the moment -
should a system copy be unavailable. Fortunately libglew is now distributed
under a permissive licence.
If you want to pass 'make -C src check' you have to use the system copy,
or spend quite a bit of time cairo-fying libglew.
There you go Joonas, I don't always ignore your suggestions! This is
simple patch to allow the user to disable symbol loops in case the
auto-detection fails on some obscure (perhaps OpenBSD) platform. Or in
case the user really wants to trim a few bytes from a library only used
during tracing!
