Positioning actors at non-integer positions produces bad looking
text. Therefore, do centering as x + round((a-b)/2) rather than
x + (a-b)/2. (This does mean that centering will be less accurate
if an actor is scaled up by a lot, but it's pretty reasonable
to assume that scaling only occurs during an effect and static
displays are unscaled.)
- include only <clutter/clutter.h>
- cogl_rectangle() takes x1/y1/x2/y2 instead of x/y/width/height
- cogl_color() renamed to cogl_set_source_color4ub()
- use explicit CoglMaterial in BigRectangle to combine a texture
and a color.
- Remove defensive calls to cogl_enable(0) - cogl_enable() no
longer exists (enable flags are part of the material)
- Use ClutterCairoTexture actor (from Clutter) rather than ClutterCairo
