add a new 32 type for framebuffer (since GL_RGB_FLOAT32_ATI is not usable with intel GPU on linux)
updated to frei0r-1.2
MSC_VER seems to have `uint32_t`

LATER check which M$VC versions have this type, and only typedef it for
those that lack it.


reapplied patch-set after migration to frei0r-1.2
simplified non-FTGL [text*] dummies

- there's no render() method (fixing FTBFS)
- remove the boilerplate; it's easier to see that these do nothing
  if we are not deluded by long comments
