Subject: st/vega: Use vgapi.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=75143ef05576ee9f25ee176bc28c3c4d03705bf5;p=mesa.git

st/vega: Use vgapi.

Rename vgFooBar to vegaFooBar and use vgapi as the dispatcher.  This
makes sure there is always a current context when the internal functions
are called.  And eglGetProcAddress is finally supported.
