converting to GL texture

| bglTexFromPixmap, is there a faster way of making a GLtexture from a pixmap. I have been experimenting with manipulating the data of a static pixmap and then replacing the texture using it, but it seems like its really slow, so I was wondering if there are other ways of doing it. Also, can mipmapping be turned off. If only using 2D, is it necessary with mipmapping as I have tried calling bglTexFromPixmap with mipmapping set as false, but then my texture gets all white and nothing else, but its much faster than with it set as true. |

| I believe that bglTexFromPixmap actually makes a call to ConvertPixmap(), which converts the pixel format whether you want it to or not. That may be what slows it down - it's a CPU routine. You can upload your own textures with OpenGL commands but you won't be able to use that in an integrated way with the standard Max2D calls. |

| I am working on something which is ment to not use Max2D if possible, so that would be alright. I will take a look around and see if I can figure out how to upload the texture directly without the conversion first. Anyone with a code example would be great. |
