4b5595b38b3884531624fab6def7c604e92d0914 is the first bad commit
commit 4b5595b38b3884531624fab6def7c604e92d0914

draw: fixup draw_find_shader_output
draw_find_shader_output like most of the code in draw used to
depend on position always being at output slot 0. which meant
that any other attribute being at 0 could signify an error.
unfortunately position can be at any of the output slots, thus
other attributes can occupy slot 0 and we need to mark the ones
which were not found by something else. This commit changes
draw_find_shader_output so that it returns -1 if it can't
find the given attribute and adjust the code that depended
on it returning >0 whenever it correctly found an attrib.
