Subject: dvi: Add image_done method to DviDevice to notify that the image is finished
X-Git-Tag: EVINCE_2_91_2~3
X-Git-Url: https://www.fi.muni.cz/~kas/git//home/kas/public_html/git/?a=commitdiff_plain;h=c565f15e696db4b4cf983cdddf1e1ab273d547dc;p=evince.git

dvi: Add image_done method to DviDevice to notify that the image is finished

This way we can mark the surface dirty when all pixels have been
modified.
