cbf5821f8e Clamp arguments for acos when calculating G_TEXTURE_GEN_LINEAR 
Fixed (Majora's Mask) Glass in Postman House not rendering #1941

Note: ucode actually works a bit differently because it uses approximated acos calculation.

c76daedfc0 Fix Worms Armageddon 
Rewrite
https://github.com/gonetz/GLideN64/commit/feb0e53034d54095464687dbae1785
4c9dc3caa6 to fix Worms Armageddon. If upper left value is zero lower
right value is scaled width minus one scaled texel.

Example:
Width = 10.0f, scale is 1.0f
urx = 0.0f;
lrx = 0.0f + 10.0f/1.0f - 1.0f/1.0f = 9.0f
Resulting range is 0-9 for a 10 texel width texture.

Fix:

dcdf66dc0b Fix hardware lighting. It was broken when lighting method was rewritten in 6af6e2c17f 
Hardware lighting is incompatible with new lighting method.
Model matrix may be different for different vartices, but only latest state of inverted light vectors are loaded to shader.
Thus I reverted calculations of data for hardware lighting.

Minor code cleanup.

89406223f5 Change texture coordinates. 
Subtracting 1 might not be accurate,
but it is done anyway in the rest of the code regarding sprites.
Just for the record, implementing correct texture coordinate handling
for sprites might need reverting this.

8985e38bc0 Fix implementation of 0xD5 (Special_1) command for F3DEX2 ucode. 
olivieryuyu found that 0xD5 command, when presents in ucode, updates combined matrix.
I could not remeber, which game uses implementation of F3DEX2_Special_1 with gSPDlistCount call.
Probably such game does not exists and this code was added by mistake. I removed it.
