Hi,
I send patches for bugzilla which refresh mathematical
formulas of the "Layer Modes" page. #601156
Some formulas are reformed.
* Multiplication signs '*' are all removed because they
can be omitted in almost regular mathematic expressions.
* Nested parentheses are changed in their sizes gradually.
Sizes are increased slightly more larger, but these file size
are reduced.
Style of formula is changed to TeX's mathematical display mode.
%% plainTeX
% multiply
$$E = {M I \over 255}$$
% divide
$$E = {256 I \over M + 1}$$
% screen
$$E = 255 - {(255-M) (255-I) \over 255}$$
% overlay
$$E = {I\over255} \left(I + {2M\over255}(255-I)\right)$$
% dodge
$$E = {256I \over (255-M) + 1}$$
% burn
$$E = 255 - {256(255-I) \over M + 1}$$
% hard light 1
$$E = 255 - { \{255 - 2(M-128)\}(255-I) \over 256},\qquad M > 128$$
% hard light 2
$$E = {2 M I \over 256},\qquad M \le 128$$
% soft light (screen)
$$R_{s} = 255 - {(255-M)(255-I) \over 255}$$
% soft light
$$E = {(255-I)M + R_{s}\over255}I$$
% addition
$$E = min\bigl( (M + I), 255\bigr)$$
% subtract
$$E = max\bigl( (I - M), 0\bigr)$$

Can this reformation be acceptable for all users?
