The Xpresent header check for PRESENT_FUTURE_VERSION but it's not set
anywhere.

Just set it to avoid a compilation issue with WError.

When using multiple buffers, no need to set all possible buffers, just
set the right number of buffers actually used per vblank backend.

Signed-off-by: Olivier Fourdan <fourdan@xfce.org>

If GLX was configured (at build time) to use multiple buffers, we would
still use a single GLX drawable.

Assign a GLX drawable per buffer instead - Note that this doesn't make
any difference in the default case, as GLX uses a single buffer anyway.

We would not allow transients for group to be minimized as long as a
parent is still visible.

Be more lenient with those, allow those to be minimized independently
of their parents.

The window menu entries would check for valid transients or modal dialog
window to enable or disable the above/below entries.

Yet the actual above/below function would simply check for any transient
or modal dialog, hence denying the request for fake dialogs without an
actual parent window.

Fix the logic to remain consistent, and allows fake dialogs to be placed
above or below other windows.

When an offscreen window is damaged, there is no need to repaint any
screen region.

Limit damage to the screen region only.

When using no vblank, with a single buffer, no need to render the entire
screen.

Optimize rendering by limiting the repaint to the damage region.

Signed-off-by: Olivier Fourdan <fourdan@xfce.org>

When using Xpresent, the compositor maintains multiple pixmap buffers
and therefore needs to accumulate damages for those multiple buffers.

However, when using GLX or no vblank method at all, there is only one
buffer pixmap and there is no need to accumulate damage between buffers.

Currently, the compositor would accumulate damage indefinitely when
using GLX or no vblank, hence damaging way more than actually necessary.

Fix this by accumulating damages only when there is more than one
buffer.

By definition, the content of the back buffer is undefined, therefore we

Typically, the opaque region applies to the client window.

When shaded, the client window is unmapped and the frame shrunk to its
minimum height.

When shaded, the opaque regio nshould simply be ignored as the client
window is no longer visible.

The opaque region was clipped against the compositor window extents,
which might be larger than the window as it can also include the drop
shadows of the server-side decorations.

Clip the opaque region against the border size and the client size if
available instead.

If the opaque region is correctly translated and intersect with the
actual window extents, there should be no need to generate additional
damages when the opaque region is updated.

Signed-off-by: Olivier Fourdan <fourdan@xfce.org>

The opaque region is set by the client, and applies to the client
window.

Therefore the opaque region should be translated to match the actual
client window, not the composited windows which may be the window
manager frame window.

We now store the current tile mode along with the client, that makes it
possible to toggle back and forth between tile modes and back to the
