2.2.7.75 MILCMD_GLYPHBITMAP
The MILCMD_GLYPHBITMAP message is a payload of the MILCMD_GLYPHCACHE_ADDBITMAPS (section 2.2.7.63) message. The MILCMD_GLYPHBITMAP is a header that describes a bitmap following the header. This payloaded bitmap contain the glyph pixels. As part of the MILCMD_GLYPHCACHE_ADDBITMAPS message, the glyph bitmaps described by MILCMD_GLYPHBITMAP are stored in the glyph cache targeted by MILCMD_GLYPHCACHE_ADDBITMAPS for later consumption by a TYPE_GLYPHRUN resource.

reserved0 (4 bytes): Can be set to any value when sent, and MUST be ignored when received.
reserved1 (4 bytes): Can be set to any value when sent, and MUST be ignored when received.
horOriginX (4 bytes): A 32-bit signed integer. Contains the offset along the X-axis that is applied (added) to the glyph anchor point to get the coordinate of the left edge of rectangle where the glyph MUST be placed. This value is used for regular text and is irrelevant when text is rendered vertically. Measured in number of bitmap elements.
horOriginY (4 bytes): A 32-bit signed integer. Contains the offset along the Y-axis that is applied (subtracted) from the glyph anchor point to get the coordinate of the top edge of rectangle where the glyph MUST be placed. This value is used for regular text and is irrelevant when text is rendered vertically. Measured in number of bitmap elements.
horAdvance (4 bytes): A 32-bit signed integer. Contains the offset along the X-axis that is subtracted from the glyph position when the text is right-to-left. Measured in number of bitmap elements.
verOriginX (4 bytes): A 32-bit signed integer. Contains the offset along the X-axis that is applied (added) to the glyph anchor point to get the coordinate of left edge of rectangle where the glyph MUST be placed. This value is used when text is rendered vertically and is irrelevant for regular text. Measured in number of bitmap elements.
verOriginY (4 bytes): A 32-bit signed integer. Contains the offset along the Y-axis that is applied (added) to the glyph anchor point to get the coordinate of top edge of rectangle where the glyph MUST be placed. This value is used when text is rendered vertically and is irrelevant for regular text. Measured in number of bitmap elements.
width (4 bytes): A 32-bit unsigned integer. Specifies the bitmap width, measured in number of bitmap elements.
height (4 bytes): A 32-bit unsigned integer. Specifies the bitmap height, measured in number of bitmap elements.
stride (4 bytes): A 32-bit unsigned integer. Specifies the bitmap stride, measured in bytes (offset between neighboring rows of bitmap). This value MUST be a multiple of 4.
