2014-01-10GRAPHICS: Fix dest alpha formula in blendPixelPtrMarcus Comstedt
The original alpha computation formula had a problem: If something was drawn on top of a pixel that was already fully opaque, there would be an overflow in the computed alpha, and the destination alpha would be truncated to 0 (fully transparent). In commit 264ba4a9 this formula was replaced with another one, which did not have overflows but also was not correct. This commits introduces a new formula, where the rounding errors have been turned in another direction; drawing a fully opaque pixel on top of a transparent one would result in a pixel which is almost, but not fully, opaque. However, this is no problem in practice, since drawing fully opaque pixels can be achieved with much less code as a special case, so add that (also improves rendering speed).
2014-01-10GRAPHICS: Fix computation of addA in darkenFill()Marcus Comstedt
The old computation had rounding issues, causing alpha to leak into the red (usually) component. There's a much easier way to compute it that does not lead to such problems: What should really happen is that the two top bits of the A component should be set to 1 (thus adding 75% alpha). So compute it that way for speed and precision.

2013-08-22GRAPHICS: Unify drawing paths in VectorRendererSpec::drawString.Johannes Schickel
Formerly, the behavior between when a drawable area was specified and when not was different in a sense which is not expected. For example, when an empty textDrawableArea was passed and the text could be drawn outside the 'area' specified. While when a textDrawableArea covering the whole screen was passed the text was clipped inside 'area'. Now, the code does follow the latter logic in both cases. I am not sure whether this will cause any issues, but a quick check of the launcher and options menu didn't reveal anything...
