passed in to CreateWindow menu should be handled.

- Add functions to attach & detach shader objects, create and delete programs, and maintain the list of programs.
- Add a list of GLSL shader programs to the device which is initialized on Init3D(), and deleted on Release().

- Declare more variable names for GLSL programs.
- Some of these won't need to be declared eventually, but it doesn't hurt to do it for now.
- Correct output name for pixel shaders (gl_FragColor instead of glFragColor).

- Got rid of the separate constant maps.
- Side effect of this is that the map is a bit larger for pixel shaders than it needs to be

- Add a new file glsl_shader.c which contains almost every GLSL specific function we'll need
- Move print_glsl_info() into glsl_shader.c
- Move the shader_reg_maps struct info into the private header, and make it part of SHADER_OPCODE_ARG.
- Create a new shared ps/vs register map for float constants (future patch will make ARB programs use this, too)

loading float constants for GLSL.

- DrawPrim is just too big of a function.  This separates the passing
  of constants to the shader into new functions.
- Fixes an off-by-one error when loading vertex declaration constants
  (should be <, not <=)
- Adds a function for GLSL loading of constants (aka Uniforms)
- Adds a GLSL program variable to the stateblock and sets it to 0 (a
  future patch will actually create this program)

Return FALSE in the WM_CLOSE PROPSHEET_DialogProc handler in order to
allow DefDlgProc to post us WM_COMMAND/IDCANCEL and unblock modal
message loop.

Include a bitmap in the resources and don't depend on Windows'
OBM_CHECK bitmap anymore.
