Beta Release  August 93 Changes:
================================
1. Added wChunkGranularity, dwIndexSize, fStepCaptureAt2x, and 
wStepCaptureAverageFrames fields to the CAPTUREPARMS structure.  

2. Added WM_CAP_FILE_SAVEDIB message to save the current frame as a
DIB.

3. Added WM_CAP_FILE_SET_INFOCHUNK message.  This allows you to embed
copyrights, keywords, etc. into your AVI file.


Alpha Release 18 May 93 Changes:
================================
1. CAPSTATUS structure has additional fields including:
        hPalCurrent     - The current palette used for capture
        fCapturingNow   - If TRUE, streaming capture in progress
        dwReturn        - Return status value at termination of capture

2. Renamed a few messages.  In particular, note a totally different
   use for capCaptureSingleFrame, vs. capGrabFrame.

3. Capture can now run as a separate task.  See updates to the
   WM_CAP_SEQUENCE and WM_CAP_SEQUENCE_NOFILE messages, or
   capCaptureSequence and capCaptureSequenceNoFile macro functions.

4. WM_CAP_SEQUENCE_STOP and WM_CAP_SEQUENCE_ABORT messages added to 
   terminate streaming capture if either yielding or running as a 
   separate task.

5. WM_CAP_PAL_MANUALCREATE message added.

6. WM_CAP_SINGLE_FRAME_OPEN... messages added to append individual
   frames to the capture file.

7. The WM_CAP_DLG_VIDEOCOMPRESSION message is not yet functional.
