OpenGL DLL for Bennu (Sandman's Worklog)
Crossplatform OpenGL for Bennu. 
Sangine vs Fenix: speedtest
Yeah so this is a speed comparison between Sangine (Sand Engine, shoot me) and Fenix. The test relies (heavily) on scaling, rotation and additive/subtractive blending, something very slow in Fenix. *grins*
Anyway, download here; start the batchfiles to start the tests, taking 10 seconds each.
This is a sneak preview, I'll fully document and do all the things necessary when the time comes. Also for now there's only a win32 preview.
Functions implemented:
* set_mode() - use set_mode(width,height,depth,2), the 2 tells the dll to use opengl (only mode implemented now!)
* load_png() - also load_image() (loads image of multiple types)
* san_update() - update the screen, call before frame; in main loop
* put()
* xput() - not region param, I do have region support implemented, but there's no region system yet
* map_put()
* map_xput()
* map_xputnp()
Excuse the lack of better documentation or process drawing support, those will come in time.

The Fenix test gives me an FPS of 5.8, the Bennu test with 'Sangine' gives me "bgdi.exe has encountered a problem and needs to close. We are sorry for the inconvenience." In addition to that I see an empty SDL_app window and cmd.exe reads "Depth: 32".

Are you running Vista? Some other info about your system? Videocard?

Still the same system as always, Windows XP SP2, Pentium M 1.73 Ghz, 2GB DDR2, Ati Mobility Radeon X700 128 MB.
Did you try it on a pc other than your own?

Yes, worked fine on Juan's and on Square's. I think your videocard does not support a certain OpenGL feature, I will have to test on this. Could you pastebin the output of glewinfo.exe?

Line 950: GL_EXT_framebuffer_object: OK [MISSING]
I think that's the culprit. I'll try to make it use a backup system (Have that already, but I guess it fails ;)). Now shopping ->

The Fenix test gives 6.7 fps, the Bennu test fails.

Eckolin's videocard doesn't support OpenGL1.4, so it fails there.

Excellent; btw my own results are:
Fenix: 5fps

I'll implement pbuffers for rendering under Windows, so backwards compatibility will be roughly 8 years instead of 3. Should be enough. Older users can make use of the software system.

After some talk with Hiperbou it became apparent his divGL (or hiperGL) does not support subtractive blending. This means an increase in FPS (because heavier stuff is not used) and the result is not the same. This explains the higher FPS result of divGL, but it's not a valid one.
Moreover, I've rewritten the thing in C, added some optimizations and the same test where I got 275FPS before I now got 325FPS, so that's a nice increase.
The current version is fully integrated in Bennu and I will post this version later.

Sandman.
I will speak to you about this but is there a chance (now that OpenGL is fully intergrated in Bennu) that you could include an HQ filter?
Or some kind of smoothing video mode without loss of contrast? This would be a good addition.
