Michael Lutz 02e8741457 Codechange: Allow for using a sprite encoder that is not the currently active blitter when loading a sprite. 2021-02-22 22:16:07 +01:00

Charles Pigott 348c231e12 Codechange: Make codestyle for CMake files consistent for 'control' statements 2020-09-25 14:43:13 +01:00
Patric Stout 56d54cf60e Add: introduce CMake for project management 
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.

Fix: inconsistent description for 32bpp-sse4-anim blitter (#7740) 2019-09-14 16:52:35 +02:00
Henry Wilson 7c8e7c6b6e Codechange: Use null pointer literal instead of the NULL macro 2019-04-10 23:22:20 +02:00
Henry Wilson af7d9020a1 Codechange: Use override specifer for overriding member declarations 
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.

Jonathan G Rennison 4b256fed36 Codechange: [Blitter] Adjust line-drawing algorithm to reduce wasted off-screen work 
This clips the line segment to be within the screen area prior to pixel iteration.

Jonathan G Rennison 0240e90169 Fix: [Blitter] Avoid signed overflow when drawing long lines 2019-01-24 11:12:06 +00:00
Jonathan G Rennison db924a4681 Codechange: [Blitter] Change DrawLine to be templated 
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.

Charles Pigott 5f86e1a390 Codechange: Silence -Wclass-memaccess warnings with GCC8 2018-06-27 22:54:46 +02:00
Jonathan G Rennison 17257b9620 Add: 32bpp SSE2 blitter palette animator (#6795) 
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.
