as hinted in my last email, Gem seems to have different hardcoded ideas
about what RGBA means (esp. on OSX)
the main confusion is about which "type" to use:
GL_UNSIGNED_INT_8_8_8_8_REV vs GL_UNSIGNED_INT_8_8_8_8
the solution seems to be simple (_REV on ppc, normal on i686) but it
seems to be done inconsistently in the source code, thus resulting in
all the alpha problems marius has reported.
i have created a wiki-page that tries to explain the technical
implementation of Gem's standard colorspaces, which can be found at
http://gem.iem.at/documentation/GemWiki/ColorSpace
i have filled this page to my best knowledge, but i would be glad if
somebody who knows what they are doing could have a look at it and
confirm (or correct) everything (esp. those lines marked with "?")
