Oh, yes, that should be relatively easy, especially since we already used to 
use GL_RGBA16F_ARB, GL_HALF_FLOAT_ARB, GLEW_ARB_texture_float or 
GLEW_ATI_texture_float where necessary. There is some fixing to do as well, 
since the deprecation of the old floating point colorspaces broke these as 
well, and we might just as well add support for 16 bit integer to the opengl 

I'm also not worried about divergent capabilities of the opengl and qpainter 
canvas: opengl already can do some things qpainter can't, like 3-d cursors, 
shaders for gradient preview and all that.
