For the CBM platforms, make revers() machine dependent and use the RVS flag of the different machines instead of a separate one. For the C128, make the textcolor() function work in 40 and 80 column mode. git-svn-id: svn://svn.cc65.org/cc65/trunk@1787 b7a2c559-68d2-44c3-8de9-860c34a00d81

Make screensize() fetch the values dynamically instead of using variables that are set on startup. This is needed to support the C128, which can switch the screen size at runtime. git-svn-id: svn://svn.cc65.org/cc65/trunk@2042 b7a2c559-68d2-44c3-8de9-860c34a00d81
