Currently, all SDL_Surfaces with an indexed pixel format have an
associated SDL_Palette. This palette either consists of entirely the
colour black, or -- in the special case of 1-bit surfaces, black and
white.
When an indexed surface is blitted to another indexed surface, a 'map'
is generated from the source surface's palette to the destination
surfaces palette, in order to preserve the look of the image if the
palettes differ.
However, in most cases, applications will want to blit the raw index
values, rather than translate to make the colours as similar as
possible. For instance, the destination surface's palette may have been
modified to fade the screen out.
This change allows an indexed surface to have no associated palette. If
either the source or destination surface of a blit do not have a
palette, then the raw indices are copied (assuming both have an indexed
format).
This mimics better what happens with most other APIs (such as
DirectDraw), where most users do not set a palette on any surface but
the screen, whose palette is implicitly used for the whole application.
These are test programs for the SDL library:
checkkeys Watch the key events to check the keyboard
loopwave Audio test -- loop playing a WAV file
testsurround Audio test -- play test tone on each audio channel
testaudioinfo Lists audio device capabilities
testerror Tests multi-threaded error handling
testfile Tests SDL_IOStream layer
testgl A very simple example of using OpenGL with SDL
testiconv Tests international string conversion
testkeys List the available keyboard keys
testloadso Tests the loadable library layer
testlocale Test Locale API
testlock Hacked up test of multi-threading and locking
testmouse Tests mouse coordinates
testmultiaudio Tests using several audio devices
testoverlay Tests the overlay flickering/scaling during playback.
testplatform Tests types, endianness and cpu capabilities
testsem Tests SDL's semaphore implementation
testshape Tests shaped windows
