Re: [Texmacs-dev] dmg image for TeXmacs/Qt/Mac with experimental support

What I don't understand is why the first window to be created renders the 
drawing surface correctly but any new buffer doesn't: a white square of roughly 
1/4 the area is displayed.

Another problem is what happens when one opens a buffer with an "automatic 
jump" to some line and column, like when browsing the scheme code with 
cmd+click. The currently visible area is greyed and one has to move around to 
force the white background.

A hack: Inside qt_tm_widget_rep::write(), SLOT_SCROLLABLE, one can force a 
resize of the scrollarea()->surface() to twice its current size. Then, when 
opening a new buffer the white drawing area is, obviously, 4 times bigger 
(though that's still not enough vertically to fill the window). The other 
problem mentioned is unaffected.
