| 29 | Description from glTexImage2D spec: |
| 30 | |
| 31 | Data is read from data as a sequence of unsigned bytes or shorts, depending on type. |
| 32 | When type is GL_UNSIGNED_BYTE, each of the bytes is interpreted as one color component. |
| 33 | When type is one of GL_UNSIGNED_SHORT_5_6_5, GL_UNSIGNED_SHORT_4_4_4_4, or |
| 34 | GL_UNSIGNED_SHORT_5_5_5_1, each unsigned short value is interpreted as containing all |
| 35 | the components for a single texel, with the color components arranged according to |
| 36 | format. Color components are treated as groups of one, two, three, or four values, |
| 37 | again based on format. Groups of components are referred to as texels. |
| 38 | |
| 39 | width × height texels are read from memory, starting at location data. By default, |
| 40 | these texels are taken from adjacent memory locations, except that after all width |
| 41 | texels are read, the read pointer is advanced to the next four-byte boundary. |
| 42 | The four-byte row alignment is specified by glPixelStorei with argument |
| 43 | GL_UNPACK_ALIGNMENT, and it can be set to one, two, four, or eight bytes. |
