* compositor.h (struct _RenderFuncs): Accept damage in
finish_render.
* egl.c (EglInitFuncs): Load eglSwapBuffersWithDamageEXT.
(FinishRender): Accept damage and swap only damaged area if
possible.
(UpdateBuffer): Always update textures.
* explicit_synchronization.c (XLSyncRelease): Fix comment.
* renderer.c (RenderFinishRender): Accept damage argument.
* subcompositor.c (ViewWidth, ViewHeight): Fix computation of
destination width and height when there is a content scale;
those values have already been adjusted into window coordinates.
(SubcompositorUpdate, SubcompositorExpose): Pass damage to
RenderFinishRender.
* surface.c (ApplyDamage): Fix some aspects of damage
calculation.
* xdg_surface.c (IsRoleMapped): Fix crash when destroying client
with subsurfaces.
(Commit, NoteBounds, ResizeForMap, XLXdgRoleSendConfigure)
(XLXdgRoleSetBoundsSize, XLXdgRoleResizeForMap): Really fix
window state reverting to maximized during unmaximization. This
had two causes: the first was that the window geometry would be
set even before ack_configure, which was fixed by moving setting
the window geometry into NoteBounds, and the second was that
NoteBounds would sometimes resize the window back to its old
dimensions if a commit (or subsurface update) happened between
SetBoundsSize and the configure event arriving, also confusing
the window manager.
* xdg_toplevel.c (NoteConfigureTime): Fix coding style.
(HandleConfigureEvent): Call SetBoundsSize before posting the
configure event.
