Bug description:  unable to select colors using palette of (loaded ) pngs or gifs

Hi,

It maybe is a problem of concept. I do not have any knowledge about the
inside, but think of following problem:

Imagine a image, saved as png and loaded with ImageCreateFromPNG. The image
has maybe 2 different colors (to be simple), but with the same RGB-value.
Ok, this does not seem to make sense, but think of a more complicated
situation.
You can get a color handle from a loaded image only with imagecolorexact or
imagecolorclosest. Both functions would maybe return the unwanted color.

So, the problem of concept as I said is maybe the kind of 'save' the image.
In a GIF I think you have a palette, so to say a table with an index and
for each index you have the RGB-values. In the image itself only the index
of a color is saved. If you now 'save' the image in the way, that you save
for each pixel the RGB-values and so do not need a palette, you loose
information. If this is the case here, I do not know a solution to the
problem that is simple. Then maybe close this bug, but please confirm it.
If it is not, then a function ImageColorExtractByIndex or something similar
would be fine.

Thanks for work on PHP, Frank
