No, I think it this should be avoided only for hardware surfaces but I
suspect the function TTF_RenderUTF8_Blended (from SDL_ttf library),
which render text for us, to create hardware surface when hardware
surfaces are available.
I am wrong, from the file (in the SDL_ttf library) SDL_ttf .c at line 1561
textbuf = SDL_AllocSurface(SDL_SWSURFACE, width, height, 32,
0x00FF0000, 0x0000FF00, 0x000000FF,
0xFF000000);
if ( textbuf == NULL ) {
return(NULL);
}
So that our text surfaces are well located in the main memory.
Is that to say that blitting a software surface to the video surface
with the glSDL backend is so slow ?
I should have forgotten something, or should be wrong somewhere.
