2017-12-30GRAPHICS: Fix incorrect call to blendFill in drawRoundedSquareShadowClipBastien Bouclet
Was broken in commit 622adff628519c16991b4edacb7283660d1630e1.
2017-12-30GRAPHICS: Speed up drawing of rounded square soft shadowsBastien Bouclet
When drawing a rounded rectangle, first its shadow is drawn, and then the rectangle proper is drawn over it. This optimization skips drawing a shadow rectangle that is entirely occluded by the main rectangle. A quick benchmark shows large improvements to the modern theme GUI draw speed. On a 1 GHz ARMv7 CPU with optimizations enabled, drawing the add game dialog @ 1920x1080 went from 976 ms to 136 ms.
2017-12-03ALL: Remove obsolete register keywordColin Snover
The register keyword was deprecated from the C++11 standard, <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4193.html#809>, and removed from the C++17 standard, <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4340>, so cannot exist in a well-formed C++17 program. It has never done anything in GCC <https://gcc.gnu.org/ml/gcc/2010-05/msg00113.html> and because of the way it is specified in the standard, it is “as meaningful as whitespace” <http://www.drdobbs.com/keywords-that-arent-or-comments-by-anoth/184403859>. The one remaining use of the register keyword is in the DS backend, where it is used to create a local register variable using the non-standard GCC Extended Asm feature. Closes gh-1079.

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.
