Whilst working on the Reproducible Builds effort [0], we noticed that
xorg-server could not be built reproducibly. One reason is because it
embeds a "current" build and date time.

... instead of its root window. Xwayland's rootless mode empties the
root window border clip since its root window has no storage, but
redirected windows (the only kind it can show) will have a non-empty
border clip anyway, cf. the #ifdef COMPOSITE in miComputeClips. With
this change, non-glamor Xwayland's GetImage actually works.
Other acceleration layers may need to change to account for this, but
this appears to be safe for the existing open source drivers. Only the
xfree86 DDX has any problem with losing its framebuffer on VT switch,
and even then only for UMS drivers (which excludes glamor, uxa, and sna
from consideration). This leaves exa, which already contains code to
evict pixmaps to host memory on VT switch. Since the xfree86 core will
still empty the root clip on VT switch, while the root window itself may
not contain a valid image we won't try to touch it, but GetImage from a
redirected window will now work even when switched away.

glamor_compute_transform_clipped_regions() uses a temporary box32
internally which is copied back to a box16 to init the regions16,
thus causing a potential overflow.
If an overflow occurs, the given region is invalid and the pixmap
init region will fail.
Simply check that the coordinates won't overflow when copying back to
the box16, avoiding a crash later down the line in glamor.

For the built in visuals, we'd typically select the "best" fbconfig
without considering the swap method. If the client then requests a
specific swap method, say GLX_SWAP_COPY_OML, it may well happen that the
first fbconfig matching requirements would have been paired with the 32-bit
compositing visual, and the client would render a potentially transparent
window.
Fix this so that we try to match fbconfigs with the same swap method to all
built-in visuals. That would guarantee that selecting a specific swap-
method would not influence the chance of getting a compositing visual.

Rather than force the caller to check first, just always return FALSE if
Composite is disabled (which is correct, since none of the visuals will

For direct contexts, most context attributes don't require any
particular awareness on the part of the server. Examples include
GLX_ARB_create_context_no_error and GLX_ARB_context_flush_control, where
all of the behavior change lives in the renderer; since that's on the
client side for a direct context, there's no reason for the X server to
validate the attribute.
The context attributes will still be validated on the client side, and
we still validate attributes for indirect contexts since the server
implementation might need to handle them. For example, the indirect
code might internally use ARB_context_flush_control for all contexts, in
which case it would need to manually emit glFlush when the client
switches between two indirect contexts that didn't request the no-flush
attribute.
