Subject: Stop reversing bytes read from the framebuffer.  That was added since
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=f6d0c970b1a357e23340b012681a9a9106d1ce64;p=openbsd

Stop reversing bytes read from the framebuffer.  That was added since
the 8x16 font showed horizontally flipped characters, but as it turns
out the issue is that with 8-bit wide fonts we use optimized rasops
code that apparently writes out the character with reversed bitorder.
