Hi,

i just wanted to show an RGB 565 image using the OpenVG emulation of mesa and i've found that MESA calculates the RGB 565 wrong.

in src/galium/state_trackers/vega/cg_translate.c
function _vega_unpack_float_span_rgba
the case for VG_sRGB_565 is calculated the following way:

clr[0] = ((*src >> 10) & 31)/31.;
clr[1] = ((*src >>  5) & 95)/95.;
clr[2] = ((*src >>  0) & 31)/31.;

That is wrong.

The correct code is:
clr[0] = ((*src >> 11) & 31)/31.;
clr[1] = ((*src >>  5) & 63)/63.;
clr[2] = ((*src >>  0) & 31)/31.;

Greetings
Andy
