Hallo IOhannes, gem-devs!

I'm not shure, but shouldn't be in pix_buffer_read ca. line 140 a

img->copy2Image(&m_pixBlock.image);

instead of

img->copy2ImageStruct(&m_pixBlock.image); ??

(but I'm not so familiar with those methods ...)

copy2Image copies all the meta-information AND the pixel-data from the given image into img. copy2ImageStruct only copies the meta-information and a reference to the data of the argument; thus it is very fast (not much copying done); the drawback is, that if the data is changed in place by a downstream object, it will be changed in the pix_buffer. i guess you just discovered that and are annoyed by it...

however, just use [pix_buf] to explicitely make a copy of the image data.

thus the user can change whether they want speed or constant data.

(so i don't really feel like changing it)
