Convert ugly comments into named structure fields. Much cleaner and less

2001-12-02  Daniel Egger  <degger@fhm.edu>

	* app/gimprc.c: Convert ugly comments into named structure fields.
	Much cleaner and less errorprone though may cause troubles on
	older compilers and then needs to be reverted. Please report!

	* app/base/base-types.h: Add FIXME reminder.

	* app/base/gimplut.c: Use CLAMP macro instead of if-cascade.

	* app/base/temp-buf.c: Remove duplicated calculations and simplify
	checks.

	* app/base/tile-manager.c:
	- (tile_manager_get_tile_num): Return success and take an additional
	  pointer for the tilenumber.
	- Simplify logic in the rest of the file as a result.
	- Remove rotten debugging cruft.

	* app/core/gimpbrushgenerated.c: Fix two stylistic nits.

	* app/app_procs.c: Include <stdlib.h> for exit () prototype.

	* app/core/gimpdrawable-blend.c: Include <stdlib.h> for abs ()
	prototype.

	* app/display/gimpdisplay.c: Include <string.h> for memcpy ()
	prototype.

	* app/core/gimpimage-convert.c: (HIST_RGB): First parameter is
	not const. Fixes a gcc warning for a wrong return value.

	* libgimpwidgets/gimpunitmenu.c
	* app/core/gimpunit.c: Add suggested (by gcc 3.1 cvs) parentheses
	to group correct logic tests together.

	* app/paint-funcs/paint-funcs-generic.h: Fix my HAS_ALPHA macro
	to avoid gcc 3.1 cvs warning.
