Define separate enum values for rotation data in both the high bits,
where it is usually kept, and the low bits, where it is sometimes used
for math or comparisons.
Define an enum value to represent the composite of the index and the
rotation, since the composite is not suitable for use as an array
subscript. Add helper functions to extract the component pieces.
This field is used in the SDL build for rendering. In the GL build, its
only purpose is for the editor to write it to a PIG file. Change that
one use to compute the value as needed. Move all other references
behind a preprocessor test for !DXX_USE_OGL. This shrinks the size of
grs_bitmap by 1 pointer, since the compiler added padding after
avg_color up to the size of the next aligned pointer.
Rename symbol OGL to DXX_USE_OGL to show that it is a DXX
symbol, not one inherited from a library. Move it to dxxsconf.h to
shorten the command line.
This is a mostly automated transform, but the changes to SConstruct were
manual.

Descent for DOS supported paging content on demand. Rebirth has no
support for paging content out, but retained piggy_page_flushed
to track whether anything had been paged out. Commit 3c20c24 ("Disable
piggy_bitmap_page_out_all") removed the last site that could set
piggy_bitmap_page_out_all to a non-zero value. All remaining code
either tests it for non-zero or sets it to zero.
Remove the statements that set it to zero.
Remove assertions that the value is zero.
Remove conditional blocks that execute only when it is non-zero.
C++ does not require this pattern.
