We can use and render the opaque region only, if we are not applying a
full-surface alpha.
Test case: weston-terminal; use super+alt+mousewheel to adjust the
window transparency. Before it went black, now it blends correctly.

Remove the weston_surface::blend attribute, which really meant that the
texture produced valid alpha values. This was used to override the opaque
region for RGBX surfaces, which produce undefined values for alpha.
Instead, compile a new shader especially for RGBX surfaces, that
hardcodes the sampled alpha as 1.0.
Before "compositor: optimize/simplify shaders" there was a 'vec4 opaque'
in the shaders, that would cause part of the texture to be forced to
alpha=1.0. Now that is gone, and we need this replacement.
To test: launch simple-shm, and use the super+alt+mousewheel combination
to make it transparent. It should not show a light cross over the window.

Re-work how the shaders and emitted vertices work. Rather than always
rendering clip-rect sized quads and doing transformation in tex coords
(and requiring the corresponding clipping in frag shader), instead
emit transformed vertices, clipped wrt. dirty region, and use simpler
frag shaders. Also, split the rendering, so blended surfaces with an
opaque region have the opaque region drawn with blend disabled. The
result is considerably fewer pixels drawn with blend enabled, and much
fewer cycles in the frag shader.
This requires having some more complex logic to figure out the vertices
of the shape which forms the intersection of the clip rect and the
transformed surface. Which has perhaps got a few bugs or missing cases,
still (visual glitches in some cases) but at this point more or less is
starting to work. I think it is at least far enough along to get some
initial review.
The result, on small SoC GPU (omap4/pandaboard) on 1920x1080 display,
for simple stuff like moving windows around, I get 60fps (before 30fps
or less), and pushing YUV buffers for hw decoded 1080p video goes from
~6fps to 30fps, with no drop in framerate for transformed/rotated video
surface.

In cases where the GPU can natively handle certain YUV formats,
eglQueryWaylandBufferWL() can return the value EGL_TEXTURE_EXTERNAL_WL
and the compositor will treat the buffer as a single egl-image-external.

This patch allows rotation and mirroring outputs for x11 and drm backends.
A new 'transform' key can be set in the [output] section. From the protocol:
"The flipped values correspond to an initial flip around a vertical axis
followed by rotation."
The transform key can be one of the following 8 strings:
normal
90
180
270
flipped
flipped-90
flipped-180
flipped-270
Instead of clearing the whole output region after a repaint, clear
only the regions that were actually painted. This way, the damage
added when a surface moves from the primary plane to another one is
kept while this region is obscured by the opaque region. This allows
the contents below an overlaid surface to be culled, but to make this
work properly, it is also necessary to change the way previous damage
is drawn.
Consider the following scenario: a surface is moved to an overlay plane
leaving some damage in the primary plane. On the following frame, the
surface on the overlay moves, revealing part of the damaged region on
the primary plane. On the frame after that, the overlaid surface moves
back to its previous position obscuring the region of the primary plane
repainted before. At this point, the repainted region was added to the
output's previous damage so that it is draw to both buffers. But since
this region is now obscured, the redrawing is skipped. If the overlaid
surface moves again revealing this region, one of the buffers actually
contains the wrong content.
To fix this problem, this patch ensures that any previous damage that
would be lost is actually preserved by folding it back into the
primary plane damage just before repainting.
We don't want to send enter/leave events to the compositor when the pointer
enters the surface, only when the pointer enters the content area. This
avoids hiding the cursor when entering the frame and sending out-of-bounds
coordinates to notify_pointer_focus().
This way we map the surface if it currently isn't mapped and avoid
duplicating some of the code already in pointer_cursor_surface_configure().
Without this, the cursor code relied on a wl_surface.attach() to show the
new pointer surface. If we're not changing the cursor buffer, we don't
get that, but we still need to map the cursor.
Replace all occurrences of workspace_damage_all_surfaces() with
weston_compositor_schedule_repaint(). This fixes a bug exposed by
982387011f where trying to switch workspaces while there are no
surfaces on the current workspace fails to start the animation.
Place the window in a random position on the output where the first seat with
a pointer is. When calculating the random position limit the range to the
area that would ensure that the whole surface is visible. If the surface is
larger than the output then the surface is placed at the origin of the
output.
This change is based on the good work of Scott Moreau <oreaus@gmail.com>
If a client sends a pong message out of the blue, we deref ping_timer
which is NULL and then crash. Unsolicited pong requests indicate that
something is wrong on the client, but the compositor should survide that.
Add a wl_seat argument to the activate and deactivate requests of
text_method.
On activation a text_model gets assigned to the input_method of the
wl_seat specified in the activate request.
This makes the separation between panels and input panels clearer and
prevents the (desktop) panel from removing existing input panels on
redraw.
The input panel layer is below the panel layer.
Not all hw supports hw cursors. Similar to the case with sprites, if
the driver does not support it, don't keep trying and spamming the log
with error messages.

They can't be imported by gbm, so no point in trying, and segfaulting
in gbm when we try to import (because it tries to deref the buffer as
a wl_drm_buffer).

A call to strcmp() is already made in output_section_done() and
output->config is set appropriately if mode is "off". There is
no need to duplicate that in create_output_for_connector().
Since weston_surface_update_transform() was changed so it called
surface_damage_below() instead of surface_damage(), the trick of
clearing the surface damage did not work anymore.
Fix this by moving the repaint surface to a special plane before
calling update_transform. The move is made manually (as opposed to
calling weston_surface_move_to_plane()) to avoid the call to
weston_surface_damage_below(). The transform update causes the
damage to be added to this special plane, which is simply ignored.
After the geometry.dirty bit is clear, the surface is moved back to
the primary plane.
When accumulating damage in the repaint loop, the opaque region of
surfaces in other planes is added to the overall opaque region. This
causes surface->clip to contain the areas obscured by surfaces in
other planes. Change it to contain only the opaque region of surfaces
in the primary plane
This fixes a bug where moving a window that was just moved from the
primary plane to another would leave artifacts on the screen. The
problem was that the damage generated by weston_surface_move_to_plane()
would be clipped on weston_surface_redraw(), leaving the contets below
it unchanged. Moving the overlaid surface would no longer generate
damage on the primary plane, so the contents would remain unchanged
(i.e. wrong) indefinitely.
To handle the case where wall clock time jumps forwards by a large amount or
backwards limit the execution of the spring calculation loop.
We do this by forcing the spring update timestamp to being no older that 1s of
the most current time we've been given. We also present a log message if the
timestamp jumps more than expected.
Input panel surfaces were kept in a list by using layer_link of
weston_surface. This was pretty hacky and resulted in the bug that
an input panel surface was not removed from the list if it was unmapped
at the time of destruction.
This patch wraps the surface in a new input_panel_surface struct and
properly handles destruction with a signal listener.
As said by krh: "Maybe we should also just call it an evdev_device
instead, shorter [and] not really ambiguous."
[krh: if my typo filled irc is going in a commit message, I'm at least going
to insert the missing words.]

This patch provides a way to define outputs for the x11 backend. It
parses [output] sections and checks for 'name' and 'mode' keys. The
'name' must start with an 'X' to distinguish from drm output names.
Command line options --width and --height supersede what is in the
config file. When --output-count is passed, the number of outputs
are limited or additional outputs added with default values.
