| * Ensure that qdrawhelper.cpp is compiled with vectorisation activeThiago Macieira2012-03-281-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The GCC option -ftree-vectorize is enabled only at level -O3, so force -O3 if this is an optimised build. Also, ensure that we're using SSE for floating point math if we're in x86 (32-bit) builds. No change is necessary for the Intel compiler, since it enables vectorisation by default at any non-zero -O level. These options are not possible with MSVC.

| * Introduce FontSmoothingGamma as a platform style hint.Friedemann Kleint2012-03-271-50/+6
| | | | | | | | | | | | | | | | | | | | - Allocate gamma tables on the heap in a thread-safe way, use font smoothing returned by the style hints of the platform to calculate them. - Improve font rendering on Windows.

* | Remove the old code using MMX registers.Thiago Macieira2012-03-281-95/+4
|/ | | | | | | | | | | | | | | | | | | There are only 8 MMX registers, each 64-bit wide, and they alias the x87 registers. The access to the MMX register cannot use the new VEX-prefix instructions either. All of the functions being replaced are either present in the qdrawhelper_sse2.cpp and qdrawhelper_ssse3.cpp files, or the plain C++ function in qdrawhelper.cpp is vectorised when compiled with -ftree-vectorize (enabled in -O3), if SSE2 support is enabled. All x86-64 processors have SSE2, so this is a net improvement for 64-bit builds. For 32-bit builds, without further support this will cause the code to use non-vector or x87 instructions, which aren't the best. The solution will come in another commit.

| * Support gamma correction of text on GLEskil Abrahamsen Blomfeldt2011-05-031-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the SRGB framebuffer extension in GL is available, we can support gamma correction of text with a gamma of 2.1. On Mac this is sufficient for gamma correcting subpixel antialiased text. Gray antialiasing should not be gamma corrected on Mac. On Windows, the user can potentially set the gamma value to anything between 1.0 and 2.2 (or something like that). We support anything that resembles 1.0 closely enough by pushing the text out without any correction (like before). We also support anything that resembles 2.1 (the gamma hardcoded in GL's SRGB extension) by turning on the extension before blending the text. In between the two, we'll use gray antialiasing to avoid differing too much from the raster engine (which is our reference in this.) For gray antialiasing on Windows, we use a constant gamma of 2.3 which has been determined by experimentation. Since this is close enough to 2.1 we do gamma correction with SRGB extension. The distance limit of 0.2 is determined by some experimentation. Reviewed-by: Samuel (cherry picked from commit 79ba7cceca5e4029876ace2121edd25b08ae14ce)
