Note on POLYGON4A Source Reference Location

Problem: When the POLYGON4A command is used under the conditions shown below, a
source reference error occurs and the same data is drawn at the rendering coordinate X = (64 × t) + 1
pixel and the following pixel (where t ≥ 1).
Conditions: Rendering attribute: WORK = 1 or STYL = 1
Source start point TXS: (32 × p) + 1 (where p ≥ 0)
Remedy: When using the POLYGON4A command under these conditions, set a value other than
(32 × p) + 1 for source start point TXS.
