drawutils regression causes blank text in drawtext filter

[Marton Balint]

Summary of the bug:

Since d645182227e8830de4de59a7b9ebec1b7e714d12 the following command does not draw any text on the video output:

./ffmpeg -f lavfi -i "testsrc=d=1,format=yuv420p" -f lavfi -i "testsrc=d=1,format=rgba" \
-filter_complex "[0:v]scale=720x576,drawtext=fontsize=220:x=64:y=256:fontfile=/usr/share/fonts/truetype/Roboto-Regular.ttf:text=TEST[v1];[v1][1:v]overlay=format=rgb[out]" \
-map "[out]" out.avi

The expected output is a big black "TEST" label on the video, the actual output has no drawn text.

Console output with debug loglevel:

% ./ffmpeg -loglevel debug -f lavfi -i "testsrc=d=1,format=yuv420p" -f lavfi -i "testsrc=d=1,format=rgba" -filter_complex "[0:v]scale=720x576,drawtext=fontsize=220:x=64:y=256:fontfile=/usr/share/fonts/truetype/Roboto-Regular.ttf:text=TEST[v1];[v1][1:v]overlay=format=rgb[out]" -map "[out]" out.avi
