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.

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

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.

d5f82bf55b (svn r27774) -Fix [FS#5889]: Enabling palette animation for 32bpp blitters 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.
