Thanks for your comments, I probably started trying to fix compiling
form the wrong end, so that I added some cruft. I'll correct the
patches accordingly.  

BTW: Since you already did a review of the EXT_sRGB_write_control
patches [1], may I kindly ask you to take another look and maybe give
your R-B if you think they are fine (in the end I was able to get virgl
suppport for it without a new cap)

Many thanks, 
Gert
