2019-09-29Fix: Some typos found using codespellJMcKiern
2019-09-14Fix: inconsistent description for 32bpp-sse4-anim blitter (#7740)glx22
2019-04-10Codechange: Use null pointer literal instead of the NULL macroHenry Wilson
2019-03-24Codechange: Use override specifer for overriding member declarationsHenry Wilson
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.
2019-01-24Codechange: [Blitter] Adjust line-drawing algorithm to reduce wasted ↵Jonathan G Rennison
off-screen work This clips the line segment to be within the screen area prior to pixel iteration.
2019-01-24Fix: [Blitter] Avoid signed overflow when drawing long linesJonathan G Rennison
2019-01-24Codechange: [Blitter] Change DrawLine to be templatedJonathan G Rennison
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.

2018-05-23Add: 32bpp SSE2 blitter palette animator (#6795)Jonathan G Rennison
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.
2018-04-10Fix: [OSX] Remove some OSX compiler warnings on newer SDKs/compilers.Michael Lutz
2017-03-30(svn r27837) -Fix (r26969): Black remap did nothing in 8bpp-simple blitter.peter1138
2017-03-18(svn r27796) -Fix [FS#6545]: 32bpp-anim blitters assumed that pitch and ↵frosch
width of the screen were equal.
2017-03-11(svn r27774) -Fix [FS#5889]: Enabling palette animation for 32bpp blitters ↵frosch
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.
2016-05-22(svn r27575) -Fix [FS#6404]: Memory leak when disabling palette animation. (JGR)frosch
2014-10-15(svn r27020) -Cleanup: some coding style consistency improvements (mostly ↵rubidium
spaces)
2014-10-06(svn r26970) -Fix (r26969): non-sse animated blitter crashed occasionallyrubidium
2014-10-06(svn r26969) -Fix (r26869): black palette didn't work very well with ↵rubidium
unmasked 32bpp sprites
2014-04-28(svn r26538) -Codechange: remove double accounting of the driversrubidium
2014-04-25(svn r26509) -Codechange: replace strdup with stredup (the latter ensures ↵rubidium
the return is not NULL)
2014-04-23(svn r26482) -Codechange: add an include that allows us to undefine/redefine ↵rubidium
"unsafe" functions to prevent them from being used, and thus having to care about certain aspects of their return values
2014-04-20(svn r26473) -Fix: make sure there is no uninitialised sprite data; the ↵rubidium
other blitters cleared the memory too
2014-04-13(svn r26463) -Fix (r10190ish): Add special handling for PALETTE_CRASH to ↵peter1138
work for non-8bpp-mapped sprites.
2014-02-11(svn r26334) -Fix: 32bit compilation.frosch
2014-01-13(svn r26260) -Codechange: add template parameters for (non) translucent and ↵rubidium
(non) animated sprites, so the least expensive variant can be chosen (MJP)
2014-01-13(svn r26259) -Codechange: add and maintain some general flags about sprites ↵rubidium
to prevent unneeded execution of expensive code (MJP)

others (MJP)

exists before attempting trying to instantiate an instance
2014-01-02(svn r26214) -Add: specialised animated SSE4 blitter (MJP)rubidium
