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.

13 To obtain the character codes corresponding to received keyboard events, Unicode translation must first be turned on using this function\&. The translation incurs a slight overhead for each keyboard event and is therefore disabled by default\&. For each subsequently received key down event, the \fBunicode\fR member of the \fI\fBSDL_keysym\fR\fR structure will then contain the corresponding character code, or zero for keysyms that do not correspond to any character code\&.

15 A value of 1 for \fBenable\fR enables Unicode translation; 0 disables it, and -1 leaves it unchanged (useful for querying the current translation mode)\&.
