72217813c6 GRIM: Do not crash on extreme FPS values. 
Easily triggered with disabled FPS limit and staying for a few seconds in
the F1 menu.

7d2f4a3185 GRIM, EMI: Avoid repeating GUIO1(GAMEOPTION_LOAD_DATAUSR). 
To ease addition of future engine-level, game-independent options.

638b841c74 TINYGL: Simplify zline.cpp . 
drawLine was broken for dx = 0 lines.
Also, the split between fillLineGeneric and drawLine, along with the many
parameters exchanged (with obscure names with subtle differences), made
the code hard to understand.
This implementation should be easier to check.
There was no visible CPU usage change.
Fixes GRIM's ticket printer, which are composed of a lot of vertical
segments.

97dc3881e0 TINYGL: Add free_texture variant taking a GLTexture * argument. 
To avoid looking texture up in the hash table when caller has a pointer to
it already. Aka, O(0) is better than O(1).

5cf904e8bc MYST3: Several fixes for the Amateria pinball puzzle

- The rotation sound effect was restarted on each frame.
- The puzzle was not showing the reset animation after the ball expiration.

c4d884967c GRIM: Reuse existing blit image. 
Fixes a memory leak when playing videos: each frame would leak as the
previous one does not get reused or freed.

ed2fdb3aba TINYGL: Correct dot-product after its sign is known. 
Normalising d when light is not in front of surface (nor behind when in
two-sides mode) is not needed as the value will not be used.
The same optimisation is already done when handling specular lights.
Also, remove "if (... > 1E-3)" conditions: as dot-product is not zero,
neither operand is zero, so this test (as a divide-by-zero protection) can
be removed.

f66026a8aa TINYGL: Only do spotlight & specular computations when actually needed. 
Spotlight and specular requires normalized d.
Skip specular if the light source or the material have no specular
component.

c7811b2d25 MYST3: Use ticks to count time instead of frames 
Ticks go by at 30 ticks per second, one tick every two frames.
This halves the speed of all game controlled animations.

03da50312b TINYGL: Move the task of writing to z-buffer to FrameBuffer::writePixel. 
Because writePixel may decide to not write anything (alpha test), in which
case no z-buffer write should happen.
Factorises code.
Fixes apparent back-face culling in GRIM behind transparent textures, like
the tube (the 3d-shape Manny takes out, not the flat image in foreground)
in set mo.

a336422811 TINYGL: Fix clipped triangle vertices alpha channel. 
In all 4 updateTmp call places, q is not initialised, so there is nothing
of value in the alpha channel (it's 0). So just apply the same rule as for
other color channels.
