* 12to11.c (MakeColormap): Delete function.
(XLMain): Stop making colormap here.
* compositor.h (ImmediateRelease): New flag.
(struct _BufferFuncs): New field can_release_now.
(struct _State): New flag `BufferAlreadyReleased'.
* egl.c (struct _CompositeProgram): New field `invert_y'.
(EglCompileCompositeProgram): Get new uniform index.
(Composite): Apply InvertY.
(egl_render_funcs): Set ImmediateRelease flag.
(BufferFromDmaBuf): Set InvertY flag if set.
(UpdateTexture, UpdateShmBufferIncrementally): Set CanRelease
flag on SHM buffers.
(UpdateBuffer): Don't update if damage is empty.
(CanReleaseNow): New function.
(egl_buffer_funcs): Add CanReleaseNow.
* picture_renderer.c (MakeCheckWindow): New function.
(FindSupportedModifiers): Use a more similar window to look for
modifiers.
(CanReleaseNow): New function.
(picture_buffer_funcs): Add CanReleaseNow.
* renderer.c (RenderCanReleaseNow): New wrapper function.
(InstallRenderer): Create colormaps here, so the buffer init
function can get it.
* shaders.txt (Composite Rectangle Fragment Shader RGBA)
(Composite Rectangle Fragment Shader RGBX)
(Composite Rectangle Fragment Shader External): New uniform
`invert_y'.
(main): Use it.
* subcompositor.c (SubcompositorUpdate): Always update attached
buffer from damage, even if damage is empty.
* surface.c (TryEarlyRelease): New function.
(InternalCommit): Call it. Also, do not call role
release_buffer hook if ImmediateRelease is specified by the
renderer.
(SavePendingState): Likewise, release buffers immediately if
possible.
* 12to11.c (XLMain): Initialize primary selections. Transfer
between X and Wayland programs is still incomplete.
* Imakefile (SRCS, OBJS): Add primary selection related objects
and sources.
(primary-selection-unstable-v1.h):
(primary-selection-unstable-v1.c): New targets.
* README: Update what is not supported.
* compositor.h: New prototypes.
* data_device.c (XLDataDeviceSendEnter): Handle resource
allocation failures.
* mime1.awk: Update generated code for changes in target entry
structures.
* seat.c (SetFocusSurface): Handle focus change for primary
selections as well.
(FindSurfaceUnder): Cut off fractional portion instead of
rounding the given coordinates, so the correct surface is found
when the cursor is moved just inside the rightmost pixel.
* surface.c (XLSurfaceRunFrameCallbacks): Handle timestamp
overflow.
* xdata.c (struct _TargetMapping): Rename atom to atom_flag, and
use it to store flags.
(MappingAtom, MappingFlag, MappingIsNextDuplicate, MappingSetFlag)

table to look up targets instead.
(CheckDuplicate): New function.
(SendOffers): Call CheckDuplicates.
(XLInitXData): Set up duplicate relationship between UTF8_STRING
and is conversion entry, and the targets mapping table.
