Add widget_set_size in the initiate time to allow smoke get the
correct surface later. Or it will report segment fault error because
of the null surface.
Also add resize_handler to not allow resizing just like flower.

Transform a menu popup the same as its parent surface.
The parent's transformation is snapshotted at the popup map() time, and
does not follow further parent motion.

Computing the real maximal opaque screen aligned rectangle of a

When a transformed (rotated) surface is continuously resized from its
top-left corner, its location will drift. This is due to accumulating
rounding errors in transforming an offset from surface-local to global
coordinates in surface_attach().
Diminish the drift down to unobservable level by changing the
weston_surface global position from integer to float.
The offset transformation is now done without rounding. To preserve the
precision, wl_shell::configure() interface must use floats, and so does
weston_surface_configure(), too.
The con of this patch is that it adds inconsistency to the surface
position coordinates: sometimes they are floats, sometimes integers.
Commit a0d6dc4f26 lost one line of code in
the refactoring, and so did not reset the surface damage on repaint
anymore. This causes damage to only accumulate, leading to a full
display redraw every cycle and hiding damage tracking issues.
Put the damage clear back.

The uniform location variables should be signed, according to the OpenGL
ES 2 specification. Moreover, GL_NONE, i.e. 0, is not an invalid nor
special location; it is actually used as a valid uniform location.
Change struct weston_shader uniform members to signed.
Stop using 0 for identifying a non-existing uniform, use -1 instead.
Furthermore, as the spec says a) glGetUniformLocation() will return -1
for non-active/existing uniforms, and b) glUniform*() function will
simply ignore all calls with location -1, we can simplify the code. We
don't have to avoid locating uniforms that don't exist, and we don't
need to test for them in weston_surface_draw() either.
Remove the micro-optimisation that avoids setting 'alpha' uniform if it
has not changed, in the name of simplification.
Unify shader creation by dropping init_solid_shader(), and calling
weston_shader_init() instead. The downside is that we compile the vertex
shader twice at startup now.

As some distros are shipping linkers, that do not resolve symbols from

Do not build toytoolkit applications that use GL, if Cairo-egl is not
available. These applications (which happen to be also the full GL
clients) do not work at all without Cairo-egl, and fail at runtime with
"unable to acquire window surface".

The x, y offsets in attach request are in surface-local coordinates, as
that is the only coordinate system the clients know about. The offset
must be transformed to global coordinate system to be applied properly.
This approximately fixes the top-left resizing of transformed surfaces.
However, it suffers from drift due to accumulating rounding errors in
continuous resizing.

This fixes the resize pointer motion vs. surface size mismatch for
right/bottom direction resizes. Top/left resizes need further fixes in
surface motion.
Additionally there is some clean-up in weston_surface_resize() to
eliminate a failure path, and fixing the Weston resize binding's resize
direction heuristic to follow transformations.

In the stack of transformations, change the rotation to be applied
to the surface before the absolute positioning. Doing so avoids having
to undo and redo the absolute positioning, and we can simply use the
surface center in local coordinates as the origin.
This fixes the surface move. Before, the surface moved along the surface
local axis, but the user expects it to move along the global axis with
the pointer.

When window_attach_surface() calls window_get_resize_dx_dy(),
window->resize_edges is cleared. However if there is already a pending
surface to be attached, the resize won't be done until the following
call to window_attach_surface(). In this next call, since resize_edges
is now zero, the top-left corner of the window will be unchanged. If
the user is resizing from the top or left border, this causes the
resize to happen in the wrong direction.
This patch changes window_attach_surface() to call
window_get_resize_dx_dy() only if an attach will actually happen.

Change weston_surface_damage*() functions to use the full surface
bounding box or call surface_compute_bbox() to find the bounding box for
an arbitrary rectangle.
This should fix all rendering artifacts for non-opaque (i.e. ARGB)
transformed surfaces.
