CMake works on all our supported platforms, like MSVC, Mingw, GCC,
Clang, and many more. It allows for a single way of doing things,
so no longer we need shell scripts and vbs scripts to work on all
our supported platforms.
Additionally, CMake allows to generate project files for like MSVC,
KDevelop, etc.
This heavily reduces the lines of code we need to support multiple
platforms from a project perspective.
Addtiionally, this heavily improves our detection of libraries, etc.

This is a C++11 feature that allows the compiler to check that a virtual
member declaration overrides a base-class member with the same signature.
Also src/blitter/32bpp_anim_sse4.hpp +38 is no longer erroneously marked
as virtual despite being a template.

off-screen work
This clips the line segment to be within the screen area prior to pixel iteration.
|
|
|
|
This is remove per-pixel overheads due to use of the SetPixel virtual
method.
These overheads included:
* expensive virtual method call which prevents inlining
* palette lookup for every pixel
* branch on whether palette animation is enabled on every pixel
Regenerate project files.

Create a new blitter mode: 32bpp-sse2-anim, which is 32bpp-anim + this.
32bpp-sse2-anim is now used by default where 32bpp-anim would have been.
Also use this with the 32bpp-sse4-anim blitter.
See issue #6469.

while paused skipped initialisation of the palette and resulted in black windows.
-Revert (r23978): No SDL-specific fix required anymore. The new fix applies to all backends.

"unsafe" functions to prevent them from being used, and thus having to care about certain aspects of their return values

other blitters cleared the memory too

With 32bpp base set about 15-20% faster in the Draw function (slower with 8bpp base set). Overall, with 32bpp base set, about 5% faster.
