[Bf-committers] improved UV test grid

[Hubert Niećko]

shuvro: did you try this BLF_draw_buffer() function ?
I think I can write addtext python function doing it pixel one by one,
but it will have one small 3x5px or 4x7 font ;) and support chars 0-9
A-F
I put array of 00 01 ... FF into image it in the middle of 32px
square, it will not be looking like on the prototype picture but
should be enough
