cc42d5cb24 TINYGL: Fix scissor testing in ztriangle. 
When dirty rectangles are enabled, fixes drawing outside (below) set scissor
rectangle.
y and pp1 must stay consistent for scissor testing to be relevant. y is
already incremented along with pp1, and pp1 does not get re-assigned on
part == 2, so do not set y either.

369332e464 TINYGL: Treat alpha the same way as other color components. 
When kLightsMode (aka kInterpRGB) is false, "a" is always 0 (vertice data is
not used in caller in corresponding branches), so taking it into account makes
all triangles transparent.
This is not visible in practice, because putPixelTextureMappingPerspective is
only called when (kInterpST || kInterpSTZ) is true, and kInterpRGB is always
true when that's the case. But unifying color processing allows further code
simplification.

e1d5b811e1 Revert "GRIM: fixed transparency in TinyGL renderer" 
This reverts commit b8bddf64da.

Since 9b7548ccf7, alpha test is enabled
when drawing model faces, fixing transparency issues in GRIM which were
corrected by reverted commit.
It is incorrect to test transparency when caller did not enable it.
Also, this change bypasses increments done at the end of
putPixelTextureMappingPerspective, so transparent textures in 16 bits mode
would be stuck on the transparent pixel for the current line's 8-pixel run
in filTriangle, and would ignore z coordinate.

  TINYGL: Optimise scissorPixel.

This does not (should not) fix any visible regression, as pixel scissor is
only (?) used when dirty rectangle mecanism is enabled (and it is disabled).

80983c1b69 TINYGL: Unroll FrameBuffer::blitOffscreenBuffer. 
This method is used to blit large buffers, so a large unrolling is still
beneficial. As it is the second hottest-spot in grim, the frame rate
increase is most significant there (compared to emi).

case), improving buffer clearing speed.

7c1a15c6e8 TINYGL: Expect colorKey in the same pixel format as surface. 
So caller does not have to depend on the pixel format used internally to
BlitImage.
Update callers which do request for color keying (GRIM/EMI only).
Also, remove a special-casing of transparent color when converting image
format which sets a color in a packed format independent from actual
destination format.
Also, in GfxTinyGL::createTextObject, prefer changing invisible colorKey
value than actually-visible color.

Vincent Pelletier
3c2689a65f TINYGL: Optimise scissorPixel. 
Scissor operations happen in a 2d rectangle, but it used to take a buffer
offset as a parameter. As a result, it had to divide that value with its
width, which is an expensive operation, which has to be done for each
pixel candidate for display (even before z-buffer comparison when
applicable, in current implementatoin).
But callers actually generate the buffer offset from rectangular
coordinates, so propagate these instead.
This sadly increases API redundancy, but saves a lot of time in a very
frequent occurrence (especially when enabling dirty rect mechanism,
which is not yet enabled by default).

drawLine was broken for dx = 0 lines.

the code hard to understand.
This implementation should be easier to check.

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.
