# The visual size of each texture is chosen in proportion to

# compression. Visually, a texture with mipmaps will be
# represented by a rectangle 33% larger than an

# There is an arbitrary limit, self.limit, which may have been

# memory utilization. We (generously) assume that the
# graphics card will implement a perfect texture packing
# algorithm, so that as long as our total utilization <=
# self.limit, it must fit within texture memory. We represent
# this visually by aggressively packing textures within the
# self.limit block so that they are guaranteed to fit, as long
# as we do not exceed the total utilization. This may
# sometimes mean distorting a texture block or even breaking
# it into multiple pieces to get it to fit, clearly
# fictionalizing whatever the graphics driver is actually
# doing.
# Internally, textures are packed into an integer grid of
# Q-units. Q-units are in proportion to texture bytes.
# Specifically, each Q-unit corresponds to a block of
# self.quantize * self.quantize texture bytes in the Texture
# Memory window. The Q-units are the smallest packable unit;
# increasing self.quantize therefore reduces the visual
# packing resolution correspondingly. Q-units very roughly
# correspond to pixels onscreen (they may be larger, sometimes
# considerably larger, than 1 pixel, depending on the window

# bytes. It is automatically adjusted in repack() based on
