Align barcodes to the left instead of center

[Copilot]

Summary

Fixed barcode alignment issue - all barcodes now align to the left edge of their container instead of being centered.

Changes Made

Modified 3 files with minimal, surgical changes:

1. RdlCri/ZxingBarcodes.cs

• Changed barcode rendering to draw at position (0,0) instead of replacing bitmap
• Use FillRectangle instead of Graphics.Clear for cross-platform compatibility
• Affects: QrCode, BarCode128, BarCode39, BarCodeEAN8, AztecCode, DataMatrix, Pdf417Barcode

2. RdlCri/BarCodeITF14.cs

• Draw barcode at position (0,0) instead of replacing bitmap
• Use FillRectangle instead of Graphics.Clear for cross-platform compatibility
• Affects: BarCodeITF14

3. RdlCri/BarCodeEAN13.cs

• Removed left quiet zone offset to start drawing from position 0
• Adjusted text positioning accordingly
• Affects: BarCodeEAN13, BarCodeBookland

Technical Details

• Lines changed: 26 insertions, 12 deletions (14 net)
• Build status: ✅ Successful (0 errors, 0 new warnings)
• Backward compatibility: This changes visual layout - barcodes will appear left-aligned instead of centered

Visual Change

Before: Barcode centered in container with padding on both sides
After: Barcode starts at left edge (0,0) with padding only on right side

Testing Notes

• Build successful with no compilation errors
• Used FillRectangle instead of Graphics.Clear for cross-platform compatibility
• Manual testing on Windows recommended to verify visual alignment
• Barcode readability and scanning should be unaffected (only position changed, not encoding)

@copilot review the check failure messages and fix the problems

'Graphics' does not contain a definition for 'Clear' and no accessible extension method 'Clear' accepting a first argument of type 'Graphics' could be found (are you missing a using directive or an assembly reference?)

Fixed in commit f3a1c92. Replaced Graphics.Clear() with FillRectangle() in both ZxingBarcodes.cs and BarCodeITF14.cs for cross-platform compatibility. Build now succeeds with 0 errors.
