I want to announce that after much development, SDL_gpu has its first
binary release! I’d appreciate it if you’d check it out and tell me what
you think. There’s only a mingw32 binary so far, but with your help I can
add more.
In case you aren’t familiar with it yet, SDL_gpu is an alternative
rendering system for SDL 1.2 and SDL 2.0. It includes everything you need
to make amazing, high-performance 2D graphics:
You can get started at the Google Code page. There’s some introductory
info, documentation, and downloads there: https://code.google.com/p/sdl-gpu/
If you see anything missing that you think would make SDL_gpu better or if
you notice any bugs, please let me know! I hope you like it and get much
use out of it!
this looks very promising. gonna check it out asap.

The only thing I want that’s not listed I think, is to be able to use
lighting effects on my to the surface. Its more useful than it sounds. I
could use it for lighting in a dungeon instead of trying to figure out how
to brighten up those pixels myself
when you rotate an gpu_image through blittransform or blitrotate, what is
the pivot point that the image rotates around? the center? topleft?

For those functions, the pivot point is the center. If you need to specify
the pivot point (in image coords), use GPU_BlitTransformX(): http://bit.ly/1erPnL7
One note for BlitTransformX is that the image will be drawn with the pivot
point aligned with the destination coords (x,y).
Yeah, you can set image wrap modes like this:
GPU_SetWrapMode(image, GPU_WRAP_REPEAT, GPU_WRAP_REPEAT);
Then blit the image with a source rect that goes beyond the image bounds,
e.g.:
GPU_Rect r = {0, 0, image->w4, image->h4};
GPU_Blit(image, &r, screen, r.w/2, r.h/2);
awesome!, so useful, i wish something like this would be in sdl textures by
default.
