[Mesa-dev] [PATCH] glx: Fix image size computation for EXT_texture_integer (v2)

[Adam Jackson]

Without this this extension basically can't work in indirect contexts,
TexImage2D will compute the image size as 0 and we'll send no image data
to the server.

v2: Add EXT_texture_integer to the client extension list too (Ian)
