Subject: Show thumbnail of the color buffer in tooltips.
X-Git-Url: https://git.cworth.org/git?a=commitdiff_plain;h=353f0535f43b54d04cc9c8080790ffac606e5b0b;p=apitrace

Show thumbnail of the color buffer in tooltips.

if we got the state for the given frame we can show
a nicer tooltip with a thumbnail of the current color buffer.
