Summary: rotating text 180 degrees fails
Initial Comment:
If I rotate text by 179.99 degrees or 180.01 degrees,
the text turns upside down, as I would expect.
If I rotate by 180.00 degrees, the text isn't rotated
at all.

Message:
The problem is caused by the assumption of the Layer_FreeType class that
the tl and br of the render description is defining a non mirrored render
description.
The stretch in all not first quadrant cases and the rotate layer in the 180
degrees rotation triggers this assumption.
It is needed to fix the Layer_FreeType class to solve this bug.

Commenting the bmp checking issue in the lyr_freetype.cpp file doesn't
seems to solve the issue.

I mean, (60,-60) mirrors it vertically properly. ;)

Message:
Stretch a text with (-60,60) doesn't mirror horizontally the text but
(60,-60) yes. I think it is related with the same issue (rotation)
There is a note in the code about a bad render in the BMP format with the
pixel height. I will see if that is causing the problem.

synfig-core/trunk/src/modules/lyr_std/rotate.cpp has specific code to
short-cut the rotation if it's 180 degrees:
if(amount.dist(Angle::deg(180))==Angle::deg(0))
I expect that's what triggers this bug.

Just leaving a note for myself that this bug is in the synfig renderer, not
synfigstudio.
