Changes from 4.2.1 to 4.2.2 RC1 (July 2007)

• Matthew Leverton added project files for MSVC 6/7/8 (see the build directory and Allegro Wiki for instructions).
  
  
• Matthew Leverton added initial support for the Digital Mars C compiler (for the Windows port). It only works with the C-only port and obj\dmc\plugins.h needs to be built by hand.

• Daniel Schlyder added a functions is_trans_font, font_has_alpha.
  
  
• Daniel Schlyder made load_txt_font() additionally search for files referenced in the font script in the same directory as the script itself. It still searches in the current working directory first (for relative paths).
  
  
• Daniel Schlyder documented that register_assert_handler() and register_trace_handler() can be called before initialising Allegro.
  
  
• Daniel Schlyder prevented the Windows port from registering its default trace handler on initialisation if the user had previously registered a custom trace handler.
  
  
• Andrei Ellman modified the 6-to-8 bit value scaling tables to be more evenly distributed, and changed the implementation of create_blender_table() to create a more evenly distributed distribution of the lower 2 bits. It should be faster as well.
  
  
• Other minor bug fixes and documentation updates.
