compositor: q&d solution for surface drift
When a transformed (rotated) surface is continuously resized from its

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

weston_surface_configure(), too.

compositor: fix and simplify shader uniform handling
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.

Previously, if a surface was transformed, it repainted as a whole,
regardless of the computed repaint region. As damage regions determine
repaint regions and whether a surface is considered for drawing at all,

transformed. Also transparent transformed surfaces were redrawn without
the surfaces below being properly redrawn, leading to alpha-saturation.
Fix that by making texture_region() use the proper global-to-surface

These results are expected with the current precision thresholds in

seeded with a constant, so the random numbers should be the same on
every run. Machine speed and scheduling affect how many iterations are
run.

compositor: implement inverse matrix transformation
Implement 4x4 matrix inversion based on LU-decomposition with partial
pivoting.
Instead of simply computing the inverse matrix explicitly, introduce the
type struct weston_inverse_matrix for storing the LU-decomposition and
the permutation from pivoting. Using doubles, this struct has greater
precision than struct weston_matrix.
If you need only few (less than 5, presumably) multiplications with the
inverse matrix, is it cheaper to use weston_inverse_matrix, and not
compute the inverse matrix explicitly into a weston_matrix.

compositor: drop inverse matrix from weston_transform
Remove the inverse matrix member from struct weston_transform. It is
easier (and probably faster, too) to create and store only forward
transformation matrices in a list, multiply them once, and then invert
the final matrix, rather than creating both forward and inverse
matrices, and multiplying both.
Add a stub for the 4x4 matrix inversion function.

compositor: implement a stack of surface transformations
Having at most one transformation object attached to a surface is not
enough anymore. If we have a surface that needs to be scaled to
fullscreen, and then we have the zoom animation, we already need two
transformations combined.
Implement support for multiple transformations by adding a transformation
list. The final transformation is the ordered composite of those in the
list. To avoid traversing the list every single time, add a dirty flag,
and cache the final transformation.
The existing transformation users (only zoom) are converted.
Note: surface drawing should honour all kinds of transformations, but
not damage region code nor input event translating code take
transformations into account, AFAICT. Therefore anything but translation
will probably behave badly until they are fixed.
