In the function renderUtf8Text() I added a variable buffer_width which
was intended to be local but I forgot the keyword "local" in front of
it. This overwrote whatever global "buffer_width" there might be and
caused a serious memory corruption described in issue #401. Although
grepping our *.lua sources did not reveal any "buffer_width" variable I
assume that there is one elsewhere (i.e. Lua's own internal namespace is
"pollutable" by user's code) because this little change definitely does
make an awful amount of difference...
1. Fix the functions sizeUtf8Text(), renderUtf8Text() and
renderUtf8TextWidth() to have a meaningful test whether to kern or not
(the current code is meaningless as it contains the `else` clause that is never
executed).
2. Whitespace changes to filechooser.lua

the framebuffer "object" now has a "member" that exposes the blitbuffer
API for the framebuffer pixmap. This allows to reuse blitting & Co for
blitbuffer-to-blitbuffer operations
this allows to render glyphs and also brings a simple
engine for rendering UTF-8 strings onto the framebuffer.
blitting to uneven offset is implemented here, too, but
needs more work and is still buggy.
In the end, this will allow for a simple GUI.
