now it looks good on MS Vista and when a user changes size of some
widgets such as a border, font size, etc.
added: spanish language to the setup (installer)
added: the setup will remove mingwm10.dll if it exists in the program directory
added: on display tab: we can select 'deg' 'rad' or 'grad' for calculating
in such functions: sin,cos,tan,cot,asin,acos,atan,acot
added: macro TTCALC_CONVERT if not defined there will not be a convert tab
(the convert tab is not finished)
added: a new icon with following dimensions: '48x48' '32x32' '16x16'
removed: parameter for gcc: -mthreads
with -mthreads it is possible (on windows) to release some kind of
'destructors' belonging to a thread when the specific thread exists
(it prevents some kind of memory leaks)
in the TTCalc when the second thread exists then there is the end
of the program and we can not use '-mthreads'
removed: file TODO (I didn't use the file)
git-svn-id: svn://ttmath.org/publicrep/ttcalc/trunk@114 e52654a7-88a9-db11-a3e9-0013d4bc506e
