Opening/closing the console when scroll bars were visible caused occasional crashes. Fixes #7089.

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: Increase robustness of VectorRendererSpec::drawString.Johannes Schickel
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...
2013-08-22GRAPHICS: Simplify VectorRendererSpec::drawString.Johannes Schickel
This removes the two additional copy steps for rendering when a drawable text area is specified. Instead it uses Surface::getSubArea to draw directly onto _activeSurface.
2013-08-19GRAPHICS: Add missing "break"s in switch, CID 1063214Torbjörn Andersson
This won't actually make any difference, since the fall through would do nothing and then reach the break in the default case. But I think it's less error-prone this way if the code is ever modified.

2013-08-08GRAPHICS: Fix VectorRendererSpec for RGBA8888.Johannes Schickel
Formerly values in the gradient and blending code overflowed and thus caused incorrect colors. Now there's some special case for 32bpp modes, which needs slightly more operations but assures a correct output.
