c84d7ebc6d shaped-texture: Get transformed textures pixels via offscreen
When a texture is transformed in any way (e.g. Wayland buffer
transforms), we cannot just fetch the pixels from the texture directly
and be done with it, as that will result in getting the untransformed
pixels.

To properly get the pixels in their right form, first draw to an
offscreen framebuffer, using the same method as when painting on the
stage, then read from the framebuffer into a cairo image surface.

1467b6b02a shaped-texture: Add support for texture transform
This adds the necessary bits to support Wayland buffer transforms.
The main part here is to properly setup the Cogl pipeline
and to recalculate the size of the painted area accordingly,
so culling etc. still works.

The choosen approach additionally lays groundwork for Wayland
wp_viewporter support.

ff08e19f52 shaped-texture: Transform clip and opaque region to texture space
The clip and opaque region are both in a translated stage coordinate
space, where the origin is in the top left corner of the painted
texture. The painting, however, is in the texture coordinate space,
so when the texture is scaled, the coordinate spaces differ.

Handle this by transforming the clip and opaque region to texture
coordinate space before computing the blend region and the opaque region
to paint.

ec8138773a compositor: Do not optimize obscured areas away in paint volumes
This optimization was presumably added before Clutter was able to
invalidate selected regions of an actor. Paint volumes are supposed
to be invariable as long as the actor conditions don't change.
Stacking of other actors shouldn't affect the paint volume, so it's
actually wrong to optimize those areas away here.

c9c3283540 shaped-texture: Disable mipmapping during animation
This avoids overwhelming the GPU with trying to update mipmaps at a high
rate. Because doing so could easily cause a reduction in the compositor
frame rate and thus actually reduce visual quality.

In the case of a window that is constantly animating in the overview,
this reduces mutter's render time by around 20%-30%.

ca1b4382c0 shaped-texture: Invalidate mask texture when main texture changes size
We currently rely only on MetaWindowActor to update the mask
texture. This isn't good enough since we might get asked to use the
mask (e.g. via meta_shaped_texture_get_image() ) after having a new
texture size but before MetaWindowActor decides to update the mask in
which case we might crash since cogl_texture_new_from_sub_texture()
might fail with an early return such as

Cogl-CRITICAL **: cogl_sub_texture_new: assertion 'sub_x + sub_width
<= next_width' failed

4c6866741d surface-actor-x11: Make sure to set a size when unredirected
When we're unredirected, we don't have a pixmap, and thus our allocation
becomes 0x0. So when events come in, they pass right through our actor,
going to the one underneath in the stack.

Fix this by having a fallback size on the shaped texture actor when
we're unredirected, causing it to always have a valid allocation.

This fixes clicking on stuff in sloppy / mouse mode focus.

The old check for using NEAREST by checking clutter_actor_is_in_clone_paint()
and meta_actor_is_untransformed (actor) doesn't work properly since
clutter_actor_is_in_clone_paint() does not look at ancestors of the
actor; it only applies to a direct clone of the actor. Using
meta_actor_painting_untransformed() allows us to check exactly what we
care about rather than using tricky approximations.

9a6a189e36 window-actor: Rebuild the shape and mask when the surface updates
Connecting to size-changed is wrong -- size-changed tells us when
we *told* the X server or resize the window. For X11, we're sort of
guaranteed that the surface will be updated at some point before the
next frame, but for Xwayland, we can't be sure that the new surface is
attached at this point.

This fixes weird artifacts when resizing apps like xclock.

be698b597b shaped-texture: Use a double when calculating clip
For x defined below, x == -INT32_MAX assuming that the arithmetic
expression actually uses the fpu.

float f = 1.0f;
int32_t x = INT32_MAX * f;

This would result in the calculated clip width/height to be -INT_MAX
if the damage width/height is INT_MAX. To solve this, use a double
variable instead.

those rectangles separately through a different path with blending turned off.

f9a11b3b18 wayland: Adds basic hybrid X + Wayland support
This adds support for running mutter as a hybrid X and Wayland
compositor. It runs a headless XWayland server for X applications
that presents wayland surfaces back to mutter which mutter can then
composite.

This aims to not break Mutter's existing support for the traditional X
compositing model which means a single build of Mutter can be
distributed supporting the traditional model and the new Wayland based
compositing model.

TODO: although building with --disable-wayland has at least been tested,
I still haven't actually verified that running as a traditional
compositor isn't broken currently.

Note: At this point no input is supported

531be6c413 Track the X Shape input region and use it for picking
We now track whether a window has an input shape specified via the X
Shape extension. Intersecting that with the bounding shape (as required
by the X Shape extension) we use the resulting rectangles to paint
window silhouettes when picking. As well as improving the correctness of
picking this should also be much more efficient because typically when
only picking solid rectangles then the need to actually render and issue
a read_pixels request can be optimized away and instead the picking is
done on the cpu.

COGL_ENABLE_EXPERIMENTAL_API in individual source files, enable
them on the command line. We weren't tracking exactly what pieces of
experimental API we were using and we were using the experimental
API in most source files that used Clutter and Cogl, so the
local #defines were annoying rather than useful.

f1aada0fae window-actor: Punt mask generation to MetaWindowActor
This effectively makes MetaShapedTexture not a MetaShapedTexture, but a simple
and dumb MetaMaskedTexture, with an optimization for clipped regions.

We're doing this as the mask may need to be more complicated than made of
a cairo path -- we eventually want GTK+ to draw the entire frame background,
which we'll then scan.

4de492eb20 shaped-texture: Remove the cairo overlay (and rounded corners)
As we want GTK+ to paint the mask on an A8, we can't simply use a cairo
path. A later commit will make this into a simple masked texture, and
meta-window-actor will be in control of the mask.

ed358c8f4b meta-texture-rectangle: Use Cogl's API to create a rectangle texture
Cogl now has public experimental API to create a rectangle texture
which we can use instead of creating a foreign texture with GL. This
avoids Mutter depending on Cogl including a GL header from its public
headers which it might not do in future.

a22859a64a shaped-texture: never slice shape mask texture
Since Cogl doesn't support multi-texturing with sliced textures and the
shape texture is combined with the texture-from-pixmap texture we need
to make sure we never construct a sliced mask texture. This patch simply
passes the COGL_TEXTURE_NO_SLICE flag to cogl_texture_from_data when
creating the shape mask texture.

d249cfd040 Pass CoglContext to cogl_texture_pixmap_x11_new()
The experimental Cogl api cogl_texture_pixmap_new() was recently changed
so it now expects an explicit CoglContext argument and it can also
return exceptions now via a GError. This patch updates mutters use of
the api accordingly.

7319b10d72 MetaShapedTexture: Remove visible_pixels_region
When we were shaping the window with a cairo region, there was an easy
optimization to restrict painting only to the pixels we were going to
actually draw. With rounded corners, the amount of work we have to do
figure out what pixels isn't worth the small savings of not drawing the
completely transparent parts of the corners, so remove this optimization,
and the supporting meta_shaped_texture_get_visible_pixels_region()

3e0ef03fd9 MetaShapedTexture: Make public and directly derive from ClutterActor
ClutterTexture has many features that we simply don't use and don't make
sense for a subclass with custom drawing. Deriving directly from ClutterActor
simplifies our code by avoiding workarounds and makes things more robust.

Additionally, make it public. GNOME Shell was already assuming that any
MetaShapedTexture was also a ClutterTexture, and we need to replace these
bits with new API for GNOME Shell to use.

fccd626604 Use a utility function to create GL_ARB_texture_rectangles
meta-texture-rectangle and meta-shaped-texture both create textures
with GL_TEXTURE_RECTANGLE_ARB as the target using direct GL
calls. This patch moves that code into a shared utility function in a
separate file instead. The function resolves the required GL symbols
dynamically instead of linking to them directly so that if Clutter
eventually stops linking to -lGL mutter will continue to build. The
function also splits the texture creation into a separate texture
creation and data upload stage so that it can use
cogl_texture_set_region to upload the data. That way it can avoid
clobbering the glPixelStore state and it can let Cogl do any necessary
format conversion. The code preserves the old value of the rectangle
texture binding instead of clobbering it because Cogl expects to be
able to cache this value to avoid redundant glBindTexture
calls. Finally, the function uses cogl_object_set_data to
automatically destroy the GL texture when the Cogl texture is
destroyed. This avoids having to have special code to destroy the cogl
texture.
