sdlSetSurfaceRle function

bool sdlSetSurfaceRle(Pointer<SdlSurface> surface, bool enabled)

Set the RLE acceleration hint for a surface.

If RLE is enabled, color key and alpha blending blits are much faster, but the surface must be locked before directly accessing the pixels.

\param surface the SDL_Surface structure to optimize. \param enabled true to enable RLE acceleration, false to disable it. \returns true on success or false on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.1.3.
