12 years agoshell: update position of surfaces with type none on map()

shell: update position of surfaces with type none on map()

Needed for implementing drag'n'drop icons. When a drag starts, the
compositor will position the top-left corner of the client supplied
icon surface at the cursor hotspot. On the first attach to that
surface, the client may want to reposition it but shell->map did not
take sx and sy parameters.

This changes shell->map interface to take sx and sy parameters and
change dekstop shell implementation to update the position of a
surface of type none according to those parameters. Since a surface
of type none won't actually be mapped, the effect of this change is
only visible for surfaces that are made visible by the compositor.

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
