Map preview doesn't draw all tiles when using SDL2

[mmatyas]

As reported here: #6 (comment)
Only happens with SDL2 build; after changing maps, only the background and the breakable blocks get drawn.

Fixed!

:D I will test this when I can.

Can confirm that it works. it plays in slowmotion on my raspberry pi though, sound is normal speed but the gameplay is maybe half the speed, not sure if its a memory thing or something specific to my pi, though I have no speed issues with the sdl1 builds on my pi.

I tested on my linux mint desktop and had no slowdown so it has something to do with the pi. I don't know why as the sdl2 builds before it was fixed didn't have any speed issues.

Could you try a completely new build? The slowdown happened to me too, but a clean build fixed that. Whoops, turned out my build had some hacks too.

The following patch fixed the issue for me on an Odroid board, can you try this on RPi? If this works, I'll add a build flag to force SW rendering.

I'll give it a test right now and see if it works

[mmatyas]

Fixed and running fast.
