From Bug #36:
There are a couple of issues with the selection of Altivec alpha-blitting
routines in CalculateAlphaBlit() in src/video/SDL_Blit_A.c.
1) There's no check for the presence of Altivec when checking if the
Blit32to565PixelAlphaAltivec() routine can be selected.
2) Altivec cannot be used in video memory, and there's no check if the
destination surface is a hardware surface. (Alpha-blitting to a hardware
surface with GPU support is a bad idea, but somebody's bound to do it anyway.)
Patch to fix these attached.

| 24 This library is distributed under GNU LGPL version 2, which can be | |
| 25 found in the file "COPYING". This license allows you to use SDL | |
| 26 freely in commercial programs as long as you link with the dynamic | |
| 27 library. | |
| 28 | |
| 29 The best way to learn how to use SDL is to check out the header files in | |
| 30 the "include" subdirectory and the programs in the "test" subdirectory. | |
| 31 The header files and test programs are well commented and always up to date. | |
| 32 More documentation is available in HTML format in "./docs/index.html" | |
| 33 | |
| 34 The test programs in the "test" subdirectory are in the public domain. | |
